A thermally stable terminal hydridozinc cation has been isolated. The nucleophilicity of the hydride ligand is demonstrated by inserting carbon dioxide, carbodiimide and benzophenone across the Zn-H bond in a facile manner. Preliminary studies on catalytic hydrosilylation using PhSiH3 indicate that the hydridozinc cation in the presence of BPh3 can selectively reduce CO2 to PhSi(OCHO)3.
