Microwave Assisted, Solvent- and Ligand-Free Copper Catalyzed N-Arylation of Phenylurea with Aryl Halides

摘要

An inexpensive and efficient catalyst system has been developed for the N-arylation of phenylurea including a variety of aryl halides. This simple protocol uses CuoO as the catalyst, microwave assisted, solvent- and ligand-free, K3PO4H2O as the base.
