This communication presents a study of the scope of the catalytic hydrogenation and hydrosilylation of chiral exomethylene-substituted cyclopentanes and cyclohexanes utilizing the organolanthanide precatalysts Cp2* LnCH(SiMe3)2 (Cp* = C5Me5; Ln = Sm, Yb). Both reaction types are sterically driven and lead to the cis-diastereomer as the major product. Additionally, the hydrosilylation is regiospecific, the silane being placed exclusively at the terminal position of the double bond.
