DOI: 10.1039/C4CC09567G, CommunicationJia Yang, Tieqiao Chen, Yongbo Zhou, Shuangfeng Yin, Li-Biao Han
The palladium-catalyzed dehydrogenative coupling of alkynes with secondary phosphine oxides is developed. Thus, in the presence of a silver additive, palladium acetate could efficiently catalyze the dehydrocoupling of secondary phosphine oxides with a variety of alkynes to produce the corresponding alkynylphosphine oxides in high yields. A reaction mechanism is proposed.
