We describe the synthesis of N-functionalised phosphinecarboxamides obtained by reaction of the 2-phosphaethynolate anion (PCO-) with diamines, specifically hydrazine, methylenediamine and ethylenediamine, in the presence of acid. The resulting neutral compounds can be deprotonated to generate phosphide anions that, when further reacted with electrophiles, form secondary phosphines.
我们描述了 N-官能化膦酰胺的合成，该合成通过 2-膦乙炔酸盐阴离子（PCO-）与二胺（具体为肼、甲脒和乙二胺）在酸存在下反应得到。所得中性化合物可以脱质子生成磷化物阴离子，当进一步与亲电试剂反应时，形成二级膦。
