Palladium-Catalyzed Cascade Oxidation/<i>sp</i>² C–H Acylation of Azoarenes with Aryl Methanes

Abstract

A Pd-catalyzed cascade oxidation/sp(2) C-H bond acylation of azoarenes was developed in which readily available aryl methanes were used as the in situ generated acyl sources. This reaction provides a convenient access to ortho-acyl azoarenes under mild conditions.
