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.
