Stoichiometric Copper or Silver Salt‐Mediated Oxidative C—H/C—H Cross‐Coupling Reactions

Abstract Over the past few years, transition metal-mediated oxidative cross-coupling reactions have emerged as a versatile method to construct C–C bonds. However, most of the precedents require high-priced precious metal catalysts such as Rh, Pd, and Ru in combination with a stoichiometric amount of metal oxidant including copper and silver salt. Recently, stoichiometric copper or silver salt-mediated oxidative C–H/C–H cross-coupling reactions in the absence of high-priced metal catalyst have shown up prominently. This short review covers the latest progress in the applications of this emerging strategy, highlights their advantages and limitations, and provides a comprehensive overview on existing procedures and employed methodologies.
