Copper Hydride Catalyzed Hydroamination of Alkenes and Alkynes

“…Although copper(I) hydride was first prepared as a polymeric solid in the 1840s, [9] well-defined, phosphine-ligated CuH complexes were not studied until the latter half of the 20 th century. [10] In the late 1980s, Stryker popularized the use of a hexameric CuH complex, [(Ph 3 P)CuH] 6 , as a mild reagent for the 1,4-reduction of α, β-unsaturated ketones and esters.…”

Copper(I)‐mediated 1,2‐ and 1,4‐Reductions

“…5.1). Proton NMR data reported by Caulton on the related [(tol) 3 P]CuH include a ''broad but structured multiplet centered on d þ3.50 in C 6 D 6 '' [16].…”

“…5.9). Triethylsilane could also be employed in place of PhMe 2 SiH, but other silyl hydrides gave either undesired mixtures of 1,4-and 1,2-products (with Ph 2 SiH 2 and (EtO) 3 SiH, for example) or no reaction (with PhCl 2 SiH, for example). Hindered enones, such as isophorone and pulegone, were not reduced under these conditions.…”

Synthesis of a Room‐Temperature‐Stable Dimeric Copper(I) Hydride

“…Discovered as early as 1844, [1] copper(I) hydride complexes have attracted considerable interest. In combination with a hydrosilane, as a hydride source, they promote the hydrosilylation of ketones and aldehydes, and they are efficient catalysts in the regioselective conjugate reduction of a number of carbonyl derivatives, including unsaturated ke-tones, aldehydes, and esters.…”
