methylenation of acyl fluorides and acyl chlorides with substituted with aryl, alkenyl, and alkyl groups trimethylaluminum afforded an array of 2-substituted propene derivatives. The addition of a catalytic amount of DPPM increased an efficiency of the reactions. Trimethylaluminum as the methylenation reagent not only eliminates the presynthesis of methylene transfer reagent, but provides an efficient method for
芳基,烯基和烷基三甲基铝取代的酰氟和酰氯的双膦膦化亚甲基化提供了一系列2取代的丙烯衍生物。催化量的DPPM的添加提高了反应效率。三甲基铝作为亚甲基化试剂,不仅消除了亚甲基转移试剂的预合成,而且为合成一系列2-取代的丙烯提供了一种有效的方法。
