Abstract
An efficient strategy for the synthesis of benzazole-phosphine ligand precursors via N-heterocyclic carbene catalyzed aerobic oxidative cyclization reaction has been performed. The reaction displays broad functional group tolerance and high atom economy, and the transformation has been further applied to benzazole-phosphine ligand synthesis.
