## Copper-catalyzed conjugate addition of organomanganese reagents to a, B ethylenic esters easily takes place in THF at O'C, in the presence of 3% CuCl and MejSiCI. Good to moderate yields are obtained from organomanganese reagents preparedfrom organolithium or organomagnesium compounok Recently,

conjugate addition reaction efficiently and the butyl manganese chloride could be indifferently prepared from butyllithium or butyhnagnesium halide. As shown in Table I and II, the scope of this reaction is very broad. Thus, high yields of 1,4-addition products were obtained from a vast array of cy
