A preliminary study of the mechanism was carried out and found that a radical intermediate is not involved. This reaction is an extension of the application of acylphosphines in Cu-catalyzed reactions and shows their potential as a phosphination reagent in the synthesis of tertiary phosphines. Key words Key wordsCu catalysis - acylphosphines - C(sp2)–P bond formation - triarylphosphine - phosphination reagent Full Text References References 1a Jiang T, Zhang H, Ding Y, Zou S, Chang R, Huang H.
