Allylic halides and α-bromoesters react with manganese metal in ethyl acetate; THF can also be used as solvent if a catalytic amount of zinc chloride is added to the reaction mixture. When the reaction is performed in the presence of various aldehydes or ketones, excellent yields of 1,2-addition products are obtained in preparative conditions.
烯丙基卤化物和α-溴酸酯与锰金属在乙酸乙酯中反应;如果将催化量的氯化锌加入到反应混合物中,则THF也可以用作溶剂。当反应在各种醛或酮的存在下进行时,在制备条件下可获得极好的1,2-加成产物收率。
