以烯二氨基钐烷基为预催化剂，研究了稀土催化的内烯烃硅氢加成反应。钐烷基配合物LSmCH 2SiMe 3（THF）2（2，L = DipNC（Me）C（Me）NDip，其中Dip = 2，6-iPr 2C 6 H3）使芳基取代的内烯烃与伯硅烷的高区域选择性硅氢加成反应成为可能，导致高产率地选择性形成一系列仲硅烷。
Rare-earth-catalyzed regioselective hydrosilylation of internal alkenes with an ene-diamido samarium alkyl as a precatalyst has been described. The samarium alkyl complex LSmCH2SiMe3(THF)2 (2, L = DipNC(Me)C(Me)NDip, where Dip = 2,6-iPr2C6H3) enabled highly regioselective hydrosilylation of aryl-substituted internal alkenes with primary silanes, leading to the selective formation of a series of secondary silanes in high yields.
