Multicomponent phosphonylation is accomplished upon the reaction of an imine with an aryne generated in situ in the presence of a dialkyl phosphite. This transition-metal-free protocol shows a broad substrate scope, providing a variety of α-aminophosphonates in moderate to good yields. A plausible mechanism for the reaction is proposed based on a deuterium exchange experiment.

通过芳烃-亚胺加合物的膦酰基化合成α-氨基膦酸酯。

在亚磷酸二烷基酯存在下,亚胺与原位生成的芳烃反应可完成多组分膦酰化反应。这种无过渡金属的方案显示了广泛的底物范围,可提供中等至良好产率的多种α-氨基膦酸酯。基于氘交换实验,提出了一种合理的反应机理。
