Selective and recyclable rhodium nanocatalysts for the reductive N-alkylation of nitrobenzenes and amines with aldehydes

Author affiliations

Abstract

Rhodium nanocatalysts were prepared and applied for the reductive N-alkylation of nitrobenzenes and amines to the corresponding secondary amines with aldehydes and ketones. Functional nitrobenzenes, such as nitrobenzenes with F, Cl, Br, CH3O and CH3 were transformed to the corresponding secondary amines in good to excellent yields. Moreover, the Rh@CN catalyzed N-alkylation of a series of primary amines with aldehydes and ketones also gave the corresponding secondary amines in high yields. The Rh@CN is heterogeneous, and can be reusable several times (at least 4 times) for the reductive N-alkylation of nitroarenes.
