Abstract

(Figure Presented) Sn two-step: Dehydrocoupllng of stannaries by the d° complex [Cp2(CI)HfH] preferentially occurs by two successive reactions (see scheme): σ-bond metathesis to form [Cp2(CI) Hf(SnH3)] and subsequent stannylene transfer into the Cp 2(CI)HF-SnH3 bond. [Cp2(CI)Hf(SnH3)] readily isomerizes to a species possessing a reactive stannylene unit, [Cp 2(CI)Hf(μH)SnH2], thus making the stannylenetransfer reaction energetically feasible.
