The radical tributyltinhydridereduction of 1,1,1,4-tetrachlorobut-2-ene yields a mixture of the expected 1,1,4-trichlorobut-2-ene and 1,1,4-trichlorobut-1-ene resulting from preferential abstraction of a chlorine atom from the trichloromethyl group. The palladium-catalyzed reduction follows an entirely different course, giving 1,1-dichlorobutadiene exclusively and quantitatively. The palladium-catalyzed
