Bakherad, Mohammad published the artcileMetal-free green synthesis of aryl amines in magnetized distilled water: experimental aspects and molecular dynamics simulation, Formula: C11H12N2O, the main research area is aryl halide secondary amine arylation magnetized water green chem; arylamine preparation.

A simple, green, and transition metal-free approach to the N-arylation of secondary amines with aryl halides in magnetized distilled water (MDW), as a solvent was introduced. This method offered the advantages of short reaction times, low costs, and an additive-free process, and it also enabled new planning strategies for the construction of aryl amine-containing pharmacophores. Also, the reaction rates were followed spectrophotometrically by monitoring the changes in the absorption spectrum of the reaction mixture in ordinary and magnetized distilled water. Furthermore, the reliable mol. dynamics (MD) simulations were used as predictive tools to interpret and describe the interactions between reactants in the ordinary and magnetized distilled water. The RDFs anal. of interactions revealed that morpholine and iodobenzene reactants were surrounded by more solvents in MDW than ordinary distilled water (ODW) 90°C. Consequently, the high reactivity observed for two reactants in MDW at 90°C can be explained by MD simulation, and there comes an established synergy between the theor. calculation and experiment

Mujahed, Shrouq published the artcileA High-Valent Ru-PCP Pincer Catalyst for Hydrogenation of Carbonyl and Carboxyl Compounds under Molecular Hydrogen, Safety of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is high valent ruthenium phosphorus carbon PCP pincer catalyst hydrogenation; carbonyl carboxyl nitrile compound hydrogenation catalyst preparation; crystal mol structure ruthenium phosphorus carbon PCP pincer complex; cooperative catalysis; esters; high-valent ruthenium; hydrogenation; pincer complexes.

Low-valent metals traditionally dominate the domain of catalytic hydrogenation. However, metal-ligand cooperating (MLC) catalytic systems, operating through heterolytic H-H bond splitting by a Lewis acidic metal and a basic ligand site, do not require an electron-rich metal. On the contrary, high-valent metals that induce weaker back donation facilitate heterolytic bond activation. Here authors report, for the first time, the efficient hydrogenation of carbonyl and carboxyl compounds under mol. hydrogen catalyzed by a structurally well-defined RuIV catalyst bearing a bifunctional PCP pincer ligand. The catalyst exhibits reactivity toward mol. hydrogen superior to that of the low-valent analog and allows hydrogen activation even at room temperature

Pieczykolan, Michal published the artcileAn Efficient Method for the Programmed Synthesis of Multifunctional Diketopyrrolopyrroles, Application In Synthesis of 100-70-9, the main research area is aldehyde primary amine nitrile diethyl oxalacetate diastereoselective cyclization fluorescence; diketopyrrolopyrrole preparation; donor-acceptor systems; dyes; fluorescence; heterocycles; lactams.

A new, transformative methodol. for the preparation of diketopyrrolopyrroles from aldehydes, primary amines, nitriles, and di-Et oxalacetate has been developed. It is now possible to prepare diketopyrrolopyrroles, e.g., I, bearing an ordered arrangement of three different substituents from abundant and com. available materials, allowing the independent regulation of all desired physicochem. properties. For the first time very electron-rich (carbazol-3-yl, dimethylaminophenyl, pyrrolo[3,2-b]pyrrolyl), and sterically hindered substituents (naphthalen-1-yl, quinolin-4-yl, acridin-9-yl, imidazo[1,5-a]pyridin-1-yl, 2-bromophenyl etc.) can be appended to the diketopyrrolopyrrole core by condensation of an appropriate nitrile with a pyrrolidin-2-one intermediate. Even greater synthetic possibilities are related to the fact that such demanding substituents as 4-dimethylaminophenyl, indol-3-yl, and 2-methoxyphenyl can be incorporated from aldehyde precursors, bypassing problems with the nitriles reactivity.

Sisko, Joseph published the artcileAn investigation of imidazole and oxazole syntheses using aryl-substituted TosMIC reagents, SDS of cas: 263389-54-4, the main research area is imidazole phenyl preparation; oxazole aryl preparation; tosylmethyl isonitrile cyclocondensation imine; amine aldehyde tosylmethyl isonitrile cyclocondensation; amino acid aldehyde tosylmethylisonitrile cyclocondensation; aldehyde ammonium hydroxide cyclization tosylmethyl isonitrile.

Efficient and mild protocols are described for preparing polysubstituted imidazoles in a single pot from aryl-substituted tosylmethyl isocyanide (TosMIC) reagents and imines generated in situ. Traditional imine-forming reactions employing virtually any aldehyde and an amine followed by addition of the TosMIC reagent gave 1,4,5-tri-substituted imidazoles with predictable regiochem. Thus, condensation of pyruvaldehyde with (MeO)2CHCH2NH2 in THF at ambient temperature for 15 min and subsequent reaction with 4-FC6H4CH(Tos)N+C- [Tos = 4-MeC6H4SO2] in the presence of piperazine for 18 h gave 71% [(fluorophenyl)imidazolyl]ethanone I. Employing chiral amines and aldehydes, particularly those derived from α-amino acids, gave imidazoles, e.g. II, with asym. centers appended to N-1 or C-5 with excellent retention of chiral purity. 1,4-Disubstituted imidazoles were also readily prepared by a simple variant of the above procedure. Selection of glyoxylic acid as the aldehyde component of the procedure lead to intermediates such as III which readily underwent decarboxylation and elimination of the tosyl moiety to give 1,4-disubstituted imidazoles in high yields. Alternatively, using NH4OH as the amine component in conjunction with a variety of aldehydes gave 4,5-disubstituted imidazoles in moderate to good yields in a single pot while avoiding the need for protecting groups. Finally, the facile preparation of mono- and disubstituted oxazoles, e.g. IV, from these TosMIC reagents and aldehydes was described.

Das, Asit Kumar published the artcileCu(OAc)2 catalysed aerobic oxidation of aldehydes to nitriles under ligand-free conditions, Safety of Picolinonitrile, the main research area is aldehyde ammonium acetate copper catalyst oxidation reaction green chem; nitrile preparation.

An economically efficient and environmentally benign approach for the direct oxidative transformation of aldehydes to nitriles was developed using com. available non-toxic copper acetate as an inexpensive catalyst and ammonium acetate as the source of nitrogen in the presence of aerial oxygen as an eco-friendly oxidant under ligand-free conditions. The reactions were associated with high yield and various sensitive moieties like allyloxy, benzyloxy, t-butyldimethylsilyloxy, hetero-aryl, formyl, keto, chloro, bromo, methylenedioxy and cyano were well tolerated in the aforesaid method. The kinetic studies showed first order dependency on the aldehyde substrate in the reaction rate. The reaction was faster with the electron deficient aldehydes as confirmed by Hammett anal. Moreover, the present oxidative method was effective on larger scales showing potential for industrial application.

O-arylcarbamoylated hydroxylamine tosylate reacts with aldehydes at room temperature to give the corresponding O-carbamoylated oximes. The reaction of carbamoylated hydroxylamine with aromatic aldehydes in THF or in toluene at reflux affords the corresponding nitriles and anilinium tosylate in high yield. Attempts to cyclize the O-carbamoylated oximes in the presence of AcCl lead again to the formation of nitriles.
