Aerobic synthesis of biocompatible copper nanoparticles: promising antibacterial agent and catalyst for nitroaromatic reduction and C–N cross coupling reaction

Abstract

Herein, we report the synthesis of copper nanoparticles at ambient conditions using biopolymer, pectin, as a protecting agent and hydrazine as a reducing agent. The obtained nanoparticles catalyze the reduction of nitroaromatic compounds in aqueous solution and also catalyze the C–N cross coupling of amines with bromobenzene in good yields.
