The stereoselective reduction of acetylenic sulfones to cis vinylic sulfones was effected by using a novel reduction system consisting of copper(II) salts (Cu(Bf4)2, Cu(OTf)2, CuF2, etc.) and a hydrosilane. The best result was obtained by the use of Cu(BF4)2. A divalent copper hydride is proposed to be responsible for this reduction.
