A copper-catalyzed system using a commercially available simple N-heterocyclic carbene ligand under atmospheric pressure of H-2 (1 atm, balloon) enables the semihydrogenation of internal alkynes, which proceeds with high Z selectivity. Thus, this copper catalysis provides a useful method for the preparation of (Z)-alkenes from internal alkynes.
