Synthesis, structure and reactivity of [TmBut]ZnH, a monomeric terminal zinc hydride compound in a sulfur-rich coordination environment: access to a heterobimetallic compound

Abstract

The first terminal zinc hydride complex that features a sulfur-rich coordination environment, namely the tris(2-mercapto-1-tert-butylimidazolyl)hydroborato compound, [Tm^But]ZnH, has been synthesized via the reaction of [Tm^But]ZnOPh with PhSiH₃. The Zn–H bond of [Tm^But]ZnH is subject to insertion of CO₂ and facile protolytic cleavage, of which the latter provides access to heterobimetallic [Tm^But]ZnMo(CO)₃Cp.
