previously used in inositol syntheses were subjected to electrochemical reduction. The unreactivity of allylic alcohols or allylic ethers at the applied potentials allowed the selective reduction of vinyl halides to olefins. Electrochemical methods provide for selective reduction of vinyl iodides over vinyl bromides, with better yields than analogous tin methodology. Cinnamyl ethers were reductively
