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.
