Fe(HSO4)3-Catalyzed Direct Conversion of Aldehydes into Nitriles Using Hydroxylamine Hydrochloride
Due to the importance and various applications of nitriles especially in medicinal productions, a new method for conversion of aldehydes to nitriles has been presented. Several nitrile-containing aromatic compounds were synthesized through the treatment of various aldehydes and hydroxylamine hydrochloride as nucleophile in the presence of ferric hydrogen sulfate as a heterogeneous, efficient, a...
متن کاملSelective synthesis of secondary amines from nitriles using Pt nanowires as a catalyst.
A new one-pot method has been developed for the selective synthesis of secondary amines via reductive amination of the corresponding nitriles using Pt nanowires as a catalyst. This method allows for the synthesis of both unsymmetrical and symmetrical secondary amines in excellent yields (up to 95%) in the presence or absence of additional amines, respectively. Furthermore, the reaction proceeds...
متن کاملSelective Hydrogenation of Nitriles to Primary Amines Catalyzed by a Polysilane/SiO2‐Supported Palladium Catalyst under Continuous‐Flow Conditions
Hydrogenation of nitriles to primary amines with heterogeneous catalysts under liquid-phase continuous-flow conditions is described. Newly developed polysilane/SiO2-supported Pd was found to be an effective catalyst and various nitriles were converted into primary amine salts in almost quantitative yields under mild reaction conditions. Interestingly, a complex mixture was obtained under batch ...
متن کاملRu-catalyzed β-selective and enantioselective addition of amines to styrenes initiated by direct arene-exchange.
A catalytic β-selective addition of amines to styrenes proceeded in the presence of cationic Ru complexes combined with diphosphine ligands. In the reaction of α-methylstyrene, an enantioselective addition was achieved by using xylylBINAP.
