A highly stereoselective alkyne semihydrogenation with copper(I) complexes is reported. Copper-N-heterocyclic carbene complex catalysts, bearing an intramolecular CuO bond, allow for the direct transfer of both hydrogen atoms from dihydrogen to the alkyne. The corresponding alkenes can be isolated with high Z selectivity and negligible overreduction to the alkane.
