Reaction of symmetrical and unsymmetrical alkynes with arylboronic acids, using PdCl2 as catalyst source and i-Pr2NPPh2 as ligand, afforded trisubstituted alkenes with regioselectivity in good to excellent yields without a common additional acetic acid. Its efficiency has been demonstrated by its good functional groups, high yield and crowded substrates.
使用PdCl 2作为催化剂源和i- Pr 2 NPPh 2作为配体,使对称和不对称炔烃与芳基硼酸反应,得到具有区域选择性的三取代烯烃,产率高至优异,而无需使用普通的额外乙酸。良好的官能团,高收率和拥挤的底物证明了其效率。
