【 摘 要 】

Catalyzed by Ir[dF(CF3)ppy](2)(dtbbpy)PF6, the coupling of potassium organotrifluoroborates with Baylis-Hillman derivatives under visible light irradiation has been developed. Based on the mechanism of reductive quenching cycle, it provides an easy, mild, efficient method for the synthesis of a variety of cep-unsaturated carboxylic esters derivatives in a broad scope of the substrates.
