An Efficient Synthesis of 1,2-Diketones by Oxidative Cross-coupling of Alkynes and Aryl Triazenes using Copper Catalysis

Abstract

An efficient and mild approach to 1,2-diketones has been developed via oxidative cross-coupling of alkynes and aryl triazenes using copper catalysis under open atmosphere. The approach is convenient, clean, and offers a wide range of substrate scope and functional group tolerance. © 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim
