Abstract

Reactions of silanes with d⁰ Ta alkylidene and Group 4 amide complexes were found to involve the initial attack on silicon atoms in the silanes by nucleophilic alkylidene carbon or amide nitrogen atoms. The reaction of (Me₃SiCH₂)₃Ta(PMe₃) [=CHSiMe₃] (1) with H₂SiR′Ph (R′ = Me, Ph) gave (Me₃SiCH₂)₃Ta[=C(SiMe₃) SiHR′Ph] (2a-b). Similar reactions of these two silanes and (H₂PhSi)₂CH₂ with (Me₃SiCH₂)Ta(PMe₃)₂ [=CHR]₂ (R = SiMe₃, 3; CMe₃, 4) yielded novel metallasilacyclobutadienes and a metalladisilacyclohexadiene, respectively. In comparison, the reactions between M(NMe₂)₄ (M = Ti, Zr, Hf) and silanes were found to give aminosilanes and metal amide hydride species which were perhaps involved in the formation of titanium-silicon-nitride (Ti-Si-N) ternary materials.
