Azizi, Kobra; Akrami, Sedigheh; Madsen, Robert published the artcile< Manganese(III) Porphyrin-Catalyzed Dehydrogenation of Alcohols to form Imines, Tertiary Amines and Quinolines>, Recommanded Product: 1-(4-Fluorophenyl)ethyl Alcohol, the main research area is manganese porphyrin chloride catalyst dehydrogenative coupling alcs amine; imine synthesis; tertiary amine synthesis; quinoline synthesis; alcohols; dehydrogenation; homogeneous catalysis; manganese; synthetic methods.

Manganese(III) porphyrin chloride complexes have been developed for the first time as catalysts for the acceptorless dehydrogenative coupling of alcs. and amines. The reaction has been applied to the direct synthesis of imines, tertiary amines and quinolines where only hydrogen gas and/or water are formed as the byproduct(s). The mechanism is believed to involve the formation of a manganese(III) alkoxide complex which degrades into the aldehyde and a manganese(III) hydride species. The latter reacts with the alc. to form hydrogen gas and thereby regenerates the alkoxide complex.

Gholinejad, Mohammad; Oftadeh, Erfan; Shojafar, Mohammad; Sansano, Jose M.; Lipshutz, Bruce H. published the artcile< Synergistic Effects of ppm Levels of Palladium on Natural Clinochlore for Reduction of Nitroarenes>, COA of Formula: C7H9NO, the main research area is aryl amine preparation green chem; nitroarene reduction pyridyltriazole clinochlore palladium nanocatalyst; clay; nitro compounds; palladium; reduction; synergistic effects.

The modified naturally occurring clay clinochlore with ppm amounts of palladium that leads to a new and very effective reagent for the reduction of numerous aromatic nitro species RNO2 (R = H3CC(O)NHC6H4, naphthalen-1-yl, pyridin-2-yl, etc.) has been augmented. When palladium nanoparticles are supported on pyridyltriazole-modified clinochlore, iron within clinochlore acts synergistically with palladium to catalyze the reduction of a wide variety of nitroarenes at room temperature in aqueous media. Based on E-factor calculations, the catalyst system is found to be in line with green chem. standards and can be recycled up to five times.

Cordell, Geoffrey A. published the artcile< 2-Halopyrroles. Synthesis and chemistry>, SDS of cas: 52160-51-7, the main research area is halopyrrole; pyrrole halogenation; benzylbromopyrrole; bromopyrrole benzyl; chloropyrrole benzyl; stability halopyrrole; electrophilic substitution halopyrrole; formylation halopyrrole; diazo coupling halopyrrole.

Following the confirmation that both 2-chloropyrrole (I) and 2-bromopyrrole (II) were unstable species, a number of 1-alkyl and C-alkyl 2-halopyrroles were synthesized to investigate the range of instability. The 1-alkyl 2-halopyrroles synthesized were 2-chloro-1-methylpyrrole (III), 2-bromo-1-methylpyrrole, 1-benzyl-2-chloropyrrole, and 1-benzyl-2-bromopyrrole. The C-alkyl-2-halopyrroles synthesized were 5-chloro-2-methylpyrrole (IV), 2-tert-butyl-5-chloropyrrole, 5-chloro-2,3,4-trimethylpyrrole (V), and 5-bromo-2,3,4-trimethylpyrrole. Also synthesized were the 1-methyl derivatives of IV and V. Electrophilic substitution of I and II under the conditions for formylation and diazo coupling was examined In the case of the latter reaction no crystalline compounds could be isolated, but diazo coupling of III gave rise to exclusive α-substitution. Formylation of I gave the α-substituted derivative but II gave a product arising from the displacement of bromine, 5-chloropyrrole-2-carboxaldehyde, in addition to 5-bromopyrrole-2-carboxaldehyde.

Takale, Balaram S.; Feng, Xiujuan; Lu, Ye; Bao, Ming; Jin, Tienan; Minato, Taketoshi; Yamamoto, Yoshinori published the artcile< Unsupported Nanoporous Gold Catalyst for Chemoselective Hydrogenation Reactions under Low Pressure: Effect of Residual Silver on the Reaction>, COA of Formula: C6H9NO, the main research area is carbonyl gold silver nanoporous chemoselective hydrogenation catalyst; alc preparation; alkyne gold silver nanoporous chemoselective hydrogenation catalyst; alkene stereoselective preparation.

For the first time, H-H dissociation on an unsupported nanoporous gold (AuNPore) surface is reported for chemoselective hydrogenation of CC, C=C, C=N, and C=O bonds under mild conditions (8 atm H2 pressure, 90 °C). Silver doping in AuNPore, which was inevitable for its preparation through a process of dealloying of Au-Ag alloy, exhibited a remarkable difference in catalytic activity between two catalysts, Au>99Ag1NPore and Au90Ag10NPore.The former was more active and the latter less active in H2 hydrogenation, while the reverse tendency was observed for O2 oxidation This marked contrast between H2 reduction and O2 oxidation is discussed. Further, Au>99Ag1NPore showed a high chemoselectivity toward reduction of terminal alkynes in the presence of internal alkynes which was not achieved using supported gold nanoparticle catalysts and other previously known methods. Reductive amination, which has great significance in synthesis of amines due to its atom-economical nature, was also realized using Au>99Ag1NPore, and the Au>99Ag1NPore/H2 system showed a preference for the reduction of aldehydes in the presence of imines. In addition to this high chemoselectivity, easy recovery and high reusability of AuNPore make it a promising heterogeneous catalyst for hydrogenation reactions.

A regio-controllable cobalt-catalyzed sequential hydrosilylation/hydroboration of arylacetylenes, delivering all the possible regio-outcomes with high regioselectivities (up to >20/1 rr for all the cases). Each regioisomer of value-added silylboronates were efficiently and regioselectively obtained from the same materials. The adjustment of the ligands of cobalt catalysts combined with dual catalysis relay strategy was the key to achieve regio-chem. control. This regio-controllable research inspired the exploration of the diversity-oriented synthesis that involved multiple additions and provided full sets of regioisomers of other synthetic useful mols.

Chakraborty, Gargi; Sikari, Rina; Mondal, Rakesh; Mandal, Sutanuva; Paul, Nanda D. published the artcile< Nickel-Catalyzed Synthesis of Pyrimidines via Dehydrogenative Functionalization of Alcohols>, Application of C8H9FO, the main research area is pyrimidine preparation; alc amidine multicomponent dehydrogenative coupling nickel catalyst.

Herein, a comparative study of nickel-catalyzed syntheses of pyrimidines via dehydrogenative multi-component coupling of alcs. and amidines using two different classes of nickel catalysts differing with respect to their mode of action during catalysis is reported. The catalysts are either two tetracoordinate Ni(II)-complexes containing two apparently redox-inactive tetraaza macrocyclic ligands or square planar Ni(II)-complexes featuring redox-active diiminosemiquinonato type scaffolds. Tetracoordinate Ni(II) catalysts dehydrogenate alcs. via a two-electron hydride transfer pathway involving energetically demanding nickel-centered redox events while in the presence of square planar Ni(II)-complexes dehydrogenation of alcs. proceeds via a one-electron hydrogen atom transfer (HAT) pathway via synergistic participation of metal and ligand centered redox processes avoiding high energy nickel centered redox events. Detailed substrate screening and control experiments were performed to unveil the reaction sequence and understand the advantages/disadvantages of these two pathways.
