Triphenylphosphine (TPP) in refluxing methanol effectively reduces maleimides 1a-g to the corresponding succinimides 2a-g in good yields. It was observed that some maleimides obtained from aromatic halogen compounds 1h-j were transformed into the corresponding succinamic acid methyl esters 3a-c by this reaction.
三苯基膦(TPP)在回流甲醇中能有效地将马来酰亚胺 1a-g 还原成相应的琥珀酰亚胺 2a-g,而且收率很高。据观察,一些从芳香卤素化合物 1h-j 中得到的马来酰亚胺通过该反应转化为相应的琥珀酰亚胺酸甲酯 3a-c。
