Regio-as well as stereo-specificreductions of a wide variety of acetylenic derivatives have been carried out in absolute ethanol with zincpowderactivated with 1,2-dibromoethane, and with zincpowderactivated successively with dibromoethane and copper(I) bromide, the first reagent less powerful and more selective than the second one.
