Catalytic N-Si coupling as a vehicle for silane dehydrocoupling via alpha-silylene elimination

摘要

Exploration of (N3N)ZrNMe2 (1, N3N = N(CH2CH2NSiMe3)(3)(3-)) as a catalyst for the cross-dehydrocoupling or heterodehydrocoupling of silanes and amines suggested silylene reactivity. Further studies of the catalysis and stoichiometric modeling reactions hint at a-silylene elimination as the pivotal mechanistic step, which expands the 3p elements known to engage in this catalysis and provides a new strategy for the catalytic generation of low-valent fragments.
