Shen, Cong; Zhu, Yuhang; Jin, Shuqi; Xu, Kejie; Luo, Shuxin; Xu, Lixia; Zhong, Guofu; Zhong, Liangjun; Zhang, Jian published the artcile< Regio- and stereo-selective olefinic C-H functionalization of aryl alkenes in ethanol>, Electric Literature of 6942-39-8, the main research area is aryl alkene palladium catalyst regioselective diastereoselective alkenylation; preparation aryl alkadiene; phenyl alkatriene preparation.
N,N-bidentate-chelation-assisted α- and β-olefinic C-H alkenylation of aryl alkenes in ethanol to afford aryl dienes/trienes with excellent regio- and stereo-selectivities was reported. The reaction of 2-alkenyl benzylamine and benzoic acid derived substrates proceeded through six-membered exo-cyclometallation and seven-membered endo-cyclometallation. The aerobic protocols feature wide functionality tolerance, high selectivities and yields, mild conditions and scalable preparation, and the directing group can be easily removed to afford Boc-protected amine by simple reduction
