Synthesis of N-arylureas in water and their N-arylation with aryl halides using copper nanoparticles loaded on natural Natrolite zeolite under ligand-free conditions
Abstract
A new method for the synthesis of N-arylureas and their N-arylation with aryl halides has been developed using copper nanoparticles supported on natural Natrolite zeolite as a reusable heterogeneous catalyst under ligand-free conditions.
