Hydride Complex

Copper(I) complexes of a new participative triphosphane ligand (<b>2<sup>H</sup></b>) have been prepared and structurally characterized, in particular [Cu(<b>2<sup>H</sup></b>)I] and [Cu(<b>2</b>)]<sub>2</sub>. Hydrogenation of the latter species afforded the trimetallic hydride species [Cu<sub>3</sub>(<b>2</b>)<sub>2</sub>(µ-H)] or in the presence of BEt<sub>3</sub>, [Cu(<b>2<sup>H</sup></b>)(HBEt<sub>3</sub>)]. Their formation evidences transient formation of [Cu(<b>2<sup>H</sup></b>)H] formed by hydrogenolysis of the Cu‒<br>N bond of [Cu(<b>2</b>)]<sub>2</sub>. [Cu(<b>2<sup>H</sup></b>)(HBEt<sub>3</sub>)] behaves like a hydride complex and inserts CO<sub>2</sub> to yield the formate product [Cu(<b>2<sup>H</sup></b>)(O<sub>2</sub>CH)].<br>

Catalytic Transfer

Catalytic transfer hydrogenations are among the most practical synthetic methods for the selective reduction of functional groups. Cheap and readily available dihydrogen (H2) equivalents are highly desirable for catalytic transfer hydrogenations, as inevitably, waste is generated by the formal H2 source. Copper hydride catalysis generally relies on stoichiometric use of waste-generating hydrosilanes. Here, we demonstrate that simple alcohols can be employed as H2 equivalents in stereoselective alkyne semihydrogenations, prototypical copper hydride-catalysed transformations.
