The reilutive amounts of 1,2 to 1,4 addition products of severa ketene dithioacetal anions to cycZic a,B-unsaturated ketones have been determined. The influence of solvent and counterion is reported. Methods have been reported recently which permit the aprotic 1,4 addition of dithiane anions to a,@u
