Abstract

An organic dye photoredox-catalyzed oxidative C-C triple bond cleavage via hydroamination leading to oxamates at room temperature has been described. The key features of this transformation are the mild conditions, metal-free organic dye as photocatalyst, broad amines scope, and a tandem hydroamination-oxidative C-C triple bond cleavage.
