Two-coordinate terminal zinc hydride complexes: synthesis, structure and preliminary reactivity studies
Abstract
The first examples of essentially two-coordinate, monomeric zinc hydride complexes, LZnH (L = –N(Ar)(SiR3)) (Ar = C6H2{C(H)Ph2}2R′-2,6,4; R = Me, R′ = Pri (L′); R = Pri, R′ = Me (L*); R = Pri, R′ = Pri (L†)) have been prepared and shown by crystallographic studies to have near linear N–Zn–H fragments. The results of computational studies imply that any Ph⋯Zn interactions in the compounds are weak at best. Preliminary reactivity studies reveal the compounds to be effective for the stoichiometric hydrozincation and catalytic hydrosilylation of carbonyl compounds.
