Organolanthanides with Cp{prime}{sub 2}Ln, R{sub 2}SiCp{double_prime} {sub 2}Ln, and R{sub 2}SiCpCp{double_prime}Ln supporting ligation (Cp{prime}={eta}{sup 5}-Me{sub 5}C{sub 5}; R = alkyl; Cp {double_prime} = {eta}{sup 5}-Me{sub 4}C{sub 5}){sup 1{minus}} catalyze olefin transformations. These characteristics caused the authors to investigate the question of whether f-element coordination geometries can elicit asymmetric transformations. A chelating ligand system designed to preserve Cp{prime}{sub 2}Ln stereoelectronic properties is presented by the authors. This system provides a rigid, chiral template for lateral/transverse substrate enantioface discrimination (A,B). Four related enantioselective organosamarium hydrogenation catalysts are considered. 25 refs., 1 fig.
