Organomanganese chloride reagents react with carboxylic acid chlorides, in THF, to give the corresponding ketones in excellent yields. The reaction is of broad scope, it is very interesting from practical and economical point of view since organomanganese chlorides (in THF) are the most stable and cheap organomanganese reagents. With methyl, aryl, alkenyl and s- or t-alkylmanganese chlorides, the acylation
有机锰氯化物试剂与羧酸氯化物在THF中反应,以优异的收率得到相应的酮。该反应的范围很广,从实用和经济的角度来看非常有趣,因为有机锰氯化物(在THF中)是最稳定和最便宜的有机锰试剂。对于甲基,芳基,烯基和仲或叔烷基锰的氯化物,酰化作用有利地在催化量的氯化铜存在下进行。该新方法允许以良好的产率制备甲基,芳基和烯基酮以及仲或叔烷基酮。
