Oxidative C-C/P-H cross-coupling is achieved via Pd-catalyzed decarbonylative cross-coupling of aroylhydrazides with P(O)H compounds. The unique cooperative reaction system, especially the Brønsted acid and bidentate phosphine ligand, allows the selective activation of the inert C-C bond and the suppression of the undesired oxidation and coordination of >P(O)-H compounds, leading to a general oxidative synthesis of aryl phosphorus compounds from easily available substrates.
