Abstract

Bimetallic Pt@Ir zigzag nanocomplexes were successfully synthesized with a uniform morphology via the simple reduction of Ir(acac)3 on the surface of Pt nanorods. The novel Pt@Ir nanocomplexes exhibited good catalytic activity in hydrogenation reactions under mild conditions, such as the hydrogenation of nitroaromatic compounds. The highest yield of the obtained product achieved was ∼99.9% using H2 as the sole reductant.

Abstract

A novel, efficient, convenient and environmentally friendly approach for the synthesis of nitriles and imines from primary amines has been developed. Using commercially available red copper as the catalyst, ammonium bromide as the co-catalyst and molecular oxygen as the sole oxidant, nitriles and imines can be afforded in high yields through benzylic oxidation.
