Guan, Zhenhong published the artcileA highly efficient catalyst for Suzuki-Miyaura coupling reaction of benzyl chloride under mild conditions, Category: nitriles-buliding-blocks, the publication is RSC Advances (2014), 4(69), 36437-36443, database is CAplus.

Diarylmethane derivatives, were synthesized in Suzuki-Miyaura coupling reaction of benzyl chloride with arylboronic acids. Pd(II) organometallic catalysts immobilized on the triphenylphosphine-functionalized microporous knitting aryl polymer (KAPs(Ph-PPh₃)-Pd) as a novel heterogeneous catalyst was employed in Suzuki-Miyaura coupling reaction of benzyl chloride and exhibited excellent catalytic activity under mild conditions with a turnover frequency (TOF) up to 76 min^-1 (4569 h^-1). This work reveals that the microporous structure of the catalyst can rapidly adsorb substrates, consequently facilitating their interaction, and eventually promoting the catalytic efficiency.

Wang, Xueqiang published the artcileMetal-Free Etherification of Aryl Methyl Ether Derivatives by C-OMe Bond Cleavage, HPLC of Formula: 261951-87-5, the publication is Organic Letters (2018), 20(14), 4267-4272, database is CAplus and MEDLINE.

Alkoxyaryl (particularly methoxyaryl) nitriles such as 2-methoxybenzonitrile underwent chemoselective etherification (nucleophilic aromatic substitution) reactions with alcs. mediated by KOt-Bu or KHMDS in 1,4-dioxane to yield different alkoxyaryl nitriles. Primary, secondary, and tertiary alcs. were effective, and natural product or pharmaceutical-derived alcs. were used; the method was used to prepare butoxycaine in three steps from 4-methoxybenzonitrile. 4-Cyanophenyl (+)-menthyl ether was converted to a variety of derivatives by nitrile functionalization reactions. DFT calculations and exptl. results are consistent with potassium ion-mediated activation of the methoxy group through binding to the nitrile and support an S_NAr mechanism for the etherification reaction.

Liu, Qiang published the artcilePalladium-Catalyzed Aerobic Oxidative Carbonylation of Arylboronate Esters under Mild Conditions, Recommanded Product: 4-(5,5-Dimethyl-1,3,2-dioxaborinan-2-yl)benzonitrile, the publication is Angewandte Chemie, International Edition (2010), 49(19), 3371-3374, S3371/1-S3371/38, database is CAplus and MEDLINE.

Oxidative carbonylation of arylboronic acid derivatives under balloon pressure of CO with air as the oxidant at 40-50 °C was used to prepare carboxylate esters. The optimized conditions for the oxidative carbonylation were 5 mol% of [PdCl₂(PPh₃)₂] as the catalyst, triethylamine as the base, and a ratio of air/CO 3:1 at 40 °C. E.g., reaction of 5,5-dimethyl-2-o-tolyl-1,3,2-dioxaborinane and BuOH under the optimized conditions gave 81% Bu 2-methylbenzoate.

Zhou, Meng published the artcileA Metal-Free Three-Component Reaction of trans-β-Nitrostyrene Derivatives, Dibromo Amides, and Amines Leading to Functionalized Amidines, COA of Formula: C9H6N2O2, the publication is Journal of Organic Chemistry (2019), 84(2), 1015-1024, database is CAplus and MEDLINE.

Amidines such as I were prepared chemoselectively and diastereoselectively by three-component reactions of β-nitrostyrenes such as (E)-PhCH:CHNO₂ with BocNBr₂ or with N,N-dibromoamides generated in situ from amides and N-bromosuccinimide or N-chlorosuccinimide. A bisamidine and α,β-unsaturated amidines were prepared using this method. The mechanism of formation of I was studied by isolation of reaction intermediates and their further reaction; the α,α-dibromonitroalkane PhCH(NHBoc)CBr₂NO₂ [formed by addition of BocNBr₂ to (E)-PhCH:CHNO₂] underwent elimination to (Z)-PhC(NHBoc):CBrNO₂ which underwent C-C bond cleavage in the presence of base and morpholine to yield I.

Tahershamsi, Leili published the artcileSynthesis, spectroscopic characterization and photoactivity of Zr(IV) phthalocyanines functionalized with aminobenzoic acids and their GO-based composites, Name: Phthalonitrile, the main research area is zirconium phthalocyanine photoactivity aminobenzoic acid graphite oxide composite.

Two complexes of bis(aminobenzoato)zirconium(IV) phthalocyanine and their graphite oxide-based composites were synthesized and characterized in respect of their photochem. properties. Structures of phthalocyanines were confirmed by Mass and IR spectroscopies. The absorption and photoluminescence spectra were investigated to show various behavior of the complexes in different media (DMSO and saline). Optical technique (monitoring variation of absorption spectra of diphenylisobenzofuran used as an indicator) was used to prove the generation of reactive oxygen species (ROS) by under light irradiation in the range of the first biol. window. The photoactivity of the materials was compared and discussed in terms of their potential ability to be used in biomedical applications, for example, as photosensitizers in photodynamic therapy.

Araghi, Mohammad Esmaeil Azim published the artcileThermal and Temporal Properties of a Thin Layer of Bromo Indium Phthalocyanine Nanostructures, Safety of Phthalonitrile, the main research area is bromo indium phthalocyanine nanostructure thermal temporal property.

In this work, we report on the synthesis, fabrication, and elec. and optical characterization of sandwich devices of bromo indium phthalocyanine thin film nanostructures in aluminum electrodes using electron beam evaporation in a high vacuum which have the potential to be used for sensing applications. The study investigate the influence of both parameters of temperature and frequency on the conduction mechanism to determine the transport process in the carriers. Results demonstrate that the capacitance, dielec. constant and loss factor decrease with increasing the frequency and increase in high temperatures The behavior of capacitance and loss factor fits well with the model of Goswami and Goswami and the results imply the domination of hopping theory. In addition, anal. of the absorption spectrum indicates that the optical band gap energy is 3 eV. Furthermore, morphol. anal. demonstrates that all films have a smooth surface with homogeneous small crystal grains with a nanoscale size order of 40 ± 10 nm. Thus, temperature and frequency-dependent experiments of optical and elec. parameters of the bromo indium phthalocyanine thin film nanostructures show their potential to be employed for sensing applications.

Guezel, Emre published the artcileHigh Photosensitized Singlet Oxygen Generating Zinc and Chloroindium Phthalocyanines Bearing (4-isopropylbenzyl)oxy Groups as Potential Agents for Photophysicochemical Applications, Category: nitriles-buliding-blocks, the main research area is oxygen zinc chloroindium phthalocyanine isopropylbenzyloxy photophysicochem application.

In this study, novel phthalonitrile derivatives (1 and 2) and their peripherally and non-peripherally tetra (4-isopropylbenzyl)oxy-substituted zinc and chloroindium phthalocyanine complexes (3-6) have been prepared for the first time. The synthesized phthalonitrile derivatives and phthalocyanine complexes were characterized spectroscopically. Not only the chloroindium phthalocyanines but also zinc phthalocyanines are essentially free from aggregation in THF at the studied micromolar concentration The purpose is to compare the effects of two types of substitution on the phthalocyanines to be used as sensitizers in photodynamic therapy (PDT). Photophys. and photochem. properties of all phthalocyanines are investigated and the results showed that the peripheral phthalocyanines more effectively photooxidize DPBF through singlet oxygen. The photochem. results showed that both ZnPc (3 and 5) and InPc (4 and 6) can be used as sensitizers in PDT because of their very high singlet oxygen quantum yields (range from 0.80 to 0.97).

Korkmaz, Aysun published the artcileAsymmetric phthalocyanines conjugated on silica for the photocatalytic degradation of organic pollutants synthesis, characterization and investigation of the photophysicochemical properties, SDS of cas: 91-15-6, the main research area is phthalocyanine silica organic pollutant photocatalytic degradation photophysicochem property.

A series of novel asym. metallo (Mg, Zn and Ga) phthalocyanines were synthesized using different ratios of starting materials. After purification, these compounds were obtained in high yields. The asym. phthalocyanines were characterized by UV-visible (UV-vis), IR (IR) and 1H NMR spectroscopy, mass spectrometry (MS) and elemental anal. High solubility in organic solvents was observed because of the ester moiety at the peripheral position, and no aggregation was observed over a wide concentration range. The photophysicochem. properties of magnesium (3a), zinc (3b) and gallium (3c) phthalocyanines were examined The highest singlet oxygen quantum yield of 0.66 was obtained for 3c. The photophysicochem. measurements demonstrate clearly the potential of these asym. phthalocyanines as photocatalytic agents in the photodegradation of organic pollutants in wastewaters. The zinc complex (3b) was attached onto silica as a solid support, and photocatalytic degradation studies were carried out using Orange G to provide a typical organic pollutant.

Bonegardt, Dmitry published the artcileHybrid materials of carbon nanotubes with fluoroalkyl- and alkyl-substituted zinc phthalocyanines, COA of Formula: C8H4N2, the main research area is carbon nanotube fuoroalkyl alkylsubstituted zinc phthalocyanine morphol humidity.

In this work, hybrid materials of single-walled carbon nanotubes (SWCNT) noncovalently functionalized with fluoroalkyl- (SWCNT/ZnPc-CF) and alkyl- (SWCNT/ZnPc-CH) substituted zinc(II) phthalocyanines were prepared The effect of fluorination of the substituents in phthalocyanine macrocycle on the functionalization degree of carbon nanotubes and sensor response to ammonia was investigated. It was shown that the type of substituents in the phthalocyanine macrocycle showed noticeable effect both on the degree of functionalization of carbon nanotubes and on the sensing performance of the investigated hybrids. The amount of phthalocyanine mols. adsorbed on SWCNT walls was shown to be 1.5 times higher in the SWCNT/ZnPc-CH hybrid. The SWCNT/ZnPc-CF layer exhibited 2 times less chemiresistive sensor response to ammonia than SWCNT/ZnPc-CH, while its sensor response was more stable at 70% relative humidity.
