Bonding and Reactivity of a μ-Hydrido Dicopper Cation

摘要

Copper hydride complexes are versatile reagents, with new applications appearing rapidly. Copper hydride was first prepared in the mid-19th century, but its structure remained unknown for more than 80 years. The characterization of [)(Ph3P)CuH)6] sparked interest in the structure and bonding of well-defined copper hydride clusters, and the use of copper in the industrial reduction of CO to methanol inspired the synthesis of copper hydride clusters through hydrogenol-ysis. Following the development of mild and selective reductions using [{(Ph3P)CuH}6], numerous methods were developed for the copper-catalyzed hydrosilylation and hydrogenation of organic substrates. Recently, Liu et al. reported a Cu_(20) cluster containing the [Cu2H5]~(3-) moiety, which releases dihydrogen upon irradiation with sunlight.
