Abstract

Organolanthanide complexes of the type Cp′2LnR (Cp′ = η5-Me5C5; Ln = La, Nd, Sm, Y, Lu; R = H, CH(SiMe3)2), Me2SiCp″2LnR (Cp″ = η5-Me4C5; Ln = Nd; R = CH(SiMe3)2), Cp′2Sm, and Cp′2Sm(THF)2 catalyze the rapid dehydrogenative oligomerization of PhSiH3. Kinetic and mechanistic arguments exclude the importance of metal-centered redox processes in the catalytic cycle and support instead "four-center" "heterolytic" bond-scission/bond-forming sequences.
