Tripodal (N-alkylated) CMP(O) and malonamide ligands: synthesis, extraction of metal ions, and potentiometric studies was written by Janczewski, Dominik;Reinhoudt, David N.;Verboom, Willem;Malinowska, Elzbieta;Pietrzak, Mariusz;Hill, Clement;Allignol, Cecile. And the article was included in New Journal of Chemistry in 2007.Synthetic Route of C15H15N3 The following contents are mentioned in the article:

Tripodal ligands build on the C-pivot (9b-e, 13b-d, and 17a-d) and trialkylbenzene platforms (10a,b, 11, 12, 14a,b, and 18a,b) bearing (N-alkylated) carbamoylmethylphosphine oxide (CMPO), carbamoylmethylphosphonate (CMP), and malonamide moieties were synthesized. Extraction studies with Am³⁺ and Eu³⁺ show that in general there is a pos. influence of the N-alkyl substituents in C-pivot CMP(O) ligands on the D (distribution) coefficients The trialkylbenzene CMPO ligands 10a,b, 11, and 12 have considerably larger D coefficients than the corresponding C-pivot analogs 9a-e, although hardly having any selectivity, while N-alkylation gives rise to smaller D coefficients Although less effective the extraction behavior of the C-pivot CMP analogs 13b-d shows more or less the same trend as the corresponding CMPO ligands 9b-e upon substitution of the carboxamide N-atom with different alkyl chains. The different malonamide ligands 17a-d and 18a,b are bad extractants, while N-alkylation makes them even worse. Potentiometric studies of CMP(O) and malonamide ligands in polymeric membranes on Pb²⁺, Cu²⁺, Ca²⁺, Mg²⁺, Na⁺, and K⁺ salts revealed that N-alkyl substituents increase the stability constants of ion-ionophore complexes compared to unsubstituted ligands. In polymeric membrane electrodes the ligands induce a selectivity pattern that differs significantly from the so-called Hofmeister series, giving the highest selectivity coefficients for UO₂²⁺ among all examined cations (Pb²⁺, Cu²⁺, Ca²⁺, Mg²⁺, Na⁺, K⁺). This study involved multiple reactions and reactants, such as 2,2′,2”-(2,4,6-Trimethylbenzene-1,3,5-triyl)triacetonitrile (cas: 16144-65-3Synthetic Route of C15H15N3).

2,2′,2”-(2,4,6-Trimethylbenzene-1,3,5-triyl)triacetonitrile (cas: 16144-65-3) belongs to nitriles. There has been no report on the microbial biosynthesis of nitriles and the physiological function of such enzymes, nor was it not even known whether aliphatic and aromatic nitriles are biological compounds or just petrochemicals. Alkyl nitriles are sufficiently acidic to undergo deprotonation of the C-H bond adjacent to the CN group.Strong bases are required, such as lithium diisopropylamide and butyl lithium. The product is referred to as a nitrile anion. Synthetic Route of C15H15N3

Cation selectivity of ionophores based on tripodal thiazole derivatives on benzene scaffold was written by Kim, Hong-Seok;Kim, Dong-Hyun;Kim, Ki Soo;Choi, Jun-Hyeak;Choi, Heung-Jin;Kim, Sung-Hoon;Shim, Jun Ho;Cha, Geun Sig;Nam, Hakhyun. And the article was included in Talanta in 2007.Synthetic Route of C15H15N3 The following contents are mentioned in the article:

The synthesis and potentiometric evaluation of new 1,3,5-tris(thiazolylcarbethoxy)-2,4,6-trimethylbenzene, 1,3,5-tris(thiazolylhydroxy)-2,4,6-trimethylbenzene, 1,3,5-tris(thiazolylmethyl)-2,4,6-trimethylbenzene, and 1,3,5-tris(thiazolylphenyl)-2,4,6-trimethylbenzene, toward mono and divalent cations under various pH conditions are outlined. The ion-selective properties of the newly synthesized compounds were studied by measuring the potentiometric responses of the 3-, 4-, 5-, and 6-based membrane electrodes to alkali metal, alk. earth metal, ammonium, and transition metal ions, under various pH conditions. The 3-based electrode exhibited a Nernstian response to ammonium and potassium under alk. pH conditions, while the other three electrodes showed a poor potentiometric performance. All electrodes showed substantial responses to silver ion under acidic condition, but there was almost nil response to other transition metal ions (Fe²⁺, Co²⁺, Zn²⁺, Ni²⁺, Pb²⁺, Cd²⁺, Cu²⁺ and Hg²⁺). The 3- and 5-based electrodes resulted in near Nernstian responses (51.3 mV and 59.5 mV/pAg⁺, resp.) with low detection limits (∼100 ppt), while the 4- and 6-based ones showed sub-Nernstian <40 mV/pAg⁺. The results were interpreted with semi-empirically modeled structures. This study involved multiple reactions and reactants, such as 2,2′,2”-(2,4,6-Trimethylbenzene-1,3,5-triyl)triacetonitrile (cas: 16144-65-3Synthetic Route of C15H15N3).

2,2′,2”-(2,4,6-Trimethylbenzene-1,3,5-triyl)triacetonitrile (cas: 16144-65-3) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.Synthetic Route of C15H15N3

Large Electro-optic Activity and Enhanced Thermal Stability from Diarylaminophenyl-Containing High-β Nonlinear Optical Chromophores was written by Cheng, Yen-Ju;Luo, Jingdong;Hau, Steven;Bale, Denise H.;Kim, Tae-Dong;Shi, Zhengwei;Lao, David B.;Tucker, Neil M.;Tian, Yanqing;Dalton, Larry R.;Reid, Philip J.;Jen, Alex K.-Y.. And the article was included in Chemistry of Materials in 2007.Category: nitriles-buliding-blocks The following contents are mentioned in the article:

Two series of highly efficient and thermally stable nonlinear optical chromophores based on the (4-diarylamino)phenyl electron donors have been synthesized and systematically investigated. A modular approach has been employed to synthesize these electron donors with tunable size, shape, and electron-donating abilities. Efficient conjugated bridges were extended from these donors and coupled with very strong CF₃-TCF electron acceptors to afford chromophores with very high β values (up to 7077 × 10^-30 esu at 1.907 μm). These chromophores possess much higher thermal stability (with their onset decomposition temperatures all above 220 °C) than those substituted with (4-dialkylamino)phenyl donors. Most importantly, the high mol. hyperpolarizability of these chromophores can be effectively translated into very large electro-optic (E-O) coefficients (r₃₃) in poled polymers through suitable shape engineering. Exemplified by the chromophore B4, which has a fluorinated aromatic substituent anchored at its donor end, it showed a very large r₃₃ (169 pm/V) at 1.31 μm. This value is almost 1 order higher than the E-O activities usually reported for (4-diarylamino)phenyl-substituted NLO chromophores. This study involved multiple reactions and reactants, such as 4-((4-Methoxyphenyl)amino)benzonitrile (cas: 319016-04-1Category: nitriles-buliding-blocks).

4-((4-Methoxyphenyl)amino)benzonitrile (cas: 319016-04-1) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).Category: nitriles-buliding-blocks

Amination with Pd-NHC Complexes: Rate and Computational Studies Involving Substituted Aniline Substrates was written by Hoi, Ka Hou;Calimsiz, Selcuk;Froese, Robert D. J.;Hopkinson, Alan C.;Organ, Michael G.. And the article was included in Chemistry – A European Journal in 2012.Application of 319016-04-1 The following contents are mentioned in the article:

The amination of aryl chlorides with various aniline derivatives using the N-heterocyclic carbene-based Pd complexes Pd-PEPPSI-IPr and Pd-PEPPSI-IPent (PEPPSI=pyridine, enhanced precatalyst, preparation, stabilization, and initiation; IPr=diisopropylphenylimidazolium derivative; IPent= diisopentylphenylimidazolium derivative) has been studied. Rate studies have shown a reliance on the aryl chloride to be electron poor, although oxidative addition is not rate limiting. Anilines couple best when they are electron rich, which would seem to discount deprotonation of the intermediate metal ammonium complex as being rate limiting in favor of reductive elimination. In previous studies with secondary amines using PEPPSI complexes, deprotonation was proposed to be the slow step in the cycle. These exptl. findings relating to mechanism were corroborated by computation. Pd-PEPPSI-IPr and the more hindered Pd-PEPPSI-IPent catalysts were used to couple deactivated aryl chlorides with electron poor anilines; while the IPr catalysis was sluggish, the IPent catalyst performed extremely well, again showing the high reactivity of this broadly useful catalyst. This study involved multiple reactions and reactants, such as 4-((4-Methoxyphenyl)amino)benzonitrile (cas: 319016-04-1Application of 319016-04-1).

And the article was included in Inorganica Chimica Acta in 2019.Application of 319016-04-1 The following contents are mentioned in the article:

Reaction of 4-R-benzaldehyde thiosemicarbazone (denoted in general as HL-R; where H stands for the dissociable acidic proton and R (R = OCH₃, CH₃, H, Cl and NO₂) for the substituent) with [Pd(dppe)(EtOH)₂]²⁺, generated in situ via interaction of [Pd(dppe)Cl₂] (dppe = 1,2-bis(diphenylphosphino)ethane) with AgNO₃ in hot ethanol, in the presence of triethylamine affords a group of orange complexes of the type [Pd(dppe)(L-R)]NO₃. Structures of [Pd(dppe)Cl₂] and [Pd(dppe)(L-OCH₃)]NO₃ have been determined by X-ray crystallog. In the [Pd(dppe)(L-R)]NO₃ complexes, the thiosemicarbazone ligands are coordinated to the metal center as monoanionic bidentate N,S-donors forming five-membered chelate rings. The [Pd(dppe)(L-R)]NO₃ complexes show intense absorptions in the visible and UV regions, which have been analyzed by TDDFT calculations All the [Pd(dppe)(L-R)]NO₃ complexes are found to efficiently catalyze Suzuki-type C-C and Buchwald-type C-N coupling reactions. This study involved multiple reactions and reactants, such as 4-((4-Methoxyphenyl)amino)benzonitrile (cas: 319016-04-1Application of 319016-04-1).

Asymmetric bioreduction of nitriles is an attractive route to produce optically active nitriles as current metal-catalyzed hydrogenations tend to have low reactivity.Application of 319016-04-1

Comparison of the effect of N-methyl and N-aryl groups on the hydrolytic stability and electronic properties of betalain dyes was written by Pioli, Renan Moraes;Mattioli, Renan Rodini;Esteves, Larissa Cerrato;Dochev, Stefan;Bastos, Erick Leite. And the article was included in Dyes and Pigments in 2020.Quality Control of 4-((4-Methoxyphenyl)amino)benzonitrile The following contents are mentioned in the article:

Betalains are antioxidant secondary metabolites that emerged as safe color additives for food and cosmetics, fluorescent dyes, and redox mediators. Herein, we describe the semisynthesis of N-Me phenylbetalain (mepBeets) and N-aryl phenylbetalain (dipBeets) dyes and compare the effect of the structure on their hydrolytic stability and electronic properties. Eight model compounds were semisynthesized by coupling betalamic acid with either N-Me anilines or N-aryl anilines in Et acetate using p-toluenesulfonic acid as catalyst. The presence of electron-withdrawing substituents in the aryl moiety of mepBeets and dipBeets results in faster hydrolysis, lower anodic potentials and increased fluorescence quantum yields compared to the corresponding unsubstituted parent compounds The results are rationalized by considering the charge distribution in the 1,7-diazaheptamethinium chromophore and are useful for the development of new hydrolytically stable betalain dyes with tunable redox and optical properties. This study involved multiple reactions and reactants, such as 4-((4-Methoxyphenyl)amino)benzonitrile (cas: 319016-04-1Quality Control of 4-((4-Methoxyphenyl)amino)benzonitrile).

4-((4-Methoxyphenyl)amino)benzonitrile (cas: 319016-04-1) belongs to nitriles. The R-C-N bond angle in and nitrile is 180° which give a nitrile functional group a linear shape. Both the carbon and the nitrogen are sp hydridized which leaves them both with two p orbitals which overlap to form the two π bond in the triple bond. Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.Quality Control of 4-((4-Methoxyphenyl)amino)benzonitrile

Molecular assembly of 1,3,5-tris(cyanomethyl) and 1,4-bis(cyanomethyl)arenes with silver triflate was written by Kilway, Kathleen V.;Deng, Shiping;Bowser, Sean;Mudd, Joseph;Washington, Laronda;Ho, Douglas M.. And the article was included in Pure and Applied Chemistry in 2006.Quality Control of 2,2′,2”-(2,4,6-Trimethylbenzene-1,3,5-triyl)triacetonitrile The following contents are mentioned in the article:

Dicyano- and tricyano-substituted aromatic angular building blocks were systematically complexed with silver triflate, and their structures were determined by single-crystal x-ray diffraction. The mol. assembly of 1,3,5-tris(cyanomethyl)-2,4,6-triethylbenzene with silver triflate from benzene resulted in a layered structure with distorted square pyramidal silver sites. The structure resulting from the complexation of 1,3,5-tris(cyanomethyl)-2,4,6-trimethylbenzene with silver triflate is dependent on the solvent of crystallization From benzene or toluene, reaction of 1,3,5-tris(cyanomethyl)-2,4,6-trimethylbenzene with silver triflate yielded a porous, channel-containing, solvated structure, but from acetone the resulting material was a network solid containing no solvent. Complexation of 1,4-bis(cyanomethyl)-2,3,5,6-tetraethylbenzene and 1,4-bis(cyanomethyl)-2,3,5,6-tetramethylbenzene with silver triflate resulted in network solids where the triflate anions were strongly coordinated to the silver.

Synthesis of new 1,3,5-tris-styryl-benzene compounds with tunable photo- and electroluminescent properties was written by Behnisch, B.;Hanack, M.. And the article was included in Synthetic Metals in 2001.Application of 16144-65-3 The following contents are mentioned in the article:

A series of 1,3,5-tris-styryl-benzene dendrimers was obtained via Knoevenagel reaction of a 1,3,5-tris-cyanomethylene benzene derivative with substituted benzaldehydes. The synthesis starting from mesitylene, followed by bromomethylation or NBS-bromination, bromo-cyano exchange, and a threefold condensation reaction leads to a conjugated system with different optical properties, depending on the substituent in the p-position (alkyl, alkoxy, amino). The photo- and electro-luminescent properties of the styryl-benzene dendrimers were studied. The addnl. Me groups at the central ring generate steric hindrance that is reflected in a strong hypsochromic shift in the UV absorption spectrum, compared to the unsubstituted analog. The series of π-conjugated dendrimers with substituent-based tunable luminescence are of interest for use in LEDs.

And the article contained the following:

The C-5 substituted 2,4-diaminoquinazoline RG3039 (compound I), a member of a chem. series that was identified and optimized using an SMN2 promoter screen, prolongs survival and improves motor function in a mouse model of spinal muscular atrophy (SMA). It is a potent inhibitor of the mRNA Decapping Scavenger Enzyme (DcpS), but the mechanism whereby DcpS inhibition leads to therapeutic benefit is unclear. Compound I is a dibasic lipophilic mol. that is predicted to accumulate in lysosomes. To understand if the in-vivo efficacy is due to DcpS inhibition or other effects resulting from the physicochem. properties of the chemotype, the authors undertook structure based mol. design to identify DcpS inhibitors with improved physicochem. properties. Herein the authors describe the design, synthesis, in-vitro pharmacol. characterization of these DcpS inhibitors along with the in-vivo mouse CNS PK profile of PF-DcpSi (compound II), one of the analogs found to be efficacious in SMA mouse model. The experimental process involved the reaction of 2-(Bromomethyl)-6-fluorobenzonitrile(cas: 1261686-95-6).SDS of cas: 1261686-95-6
