Modification of the properties of a compound can be achieved by careful selection of the substituents, the groups attached to the parent structure. Among the multitude of substituents, amino groups, by virtue of their strong pi-donating properties, have been the most heavily used in applications where a more electron rich parent structure is required. We have recently demonstrated that, in contrast to the widespread belief that amino groups are the premier pi-donor substituent, iminophosphorano substituents (R3P=N-) are even stronger in this regard. We exploited this property to prepare the most powerful neutral organic electron donors, which act as homogeneous reducing agents. In complementarity to metal-based reagents, such organic reducing agents hold the promise of allowing for alternate reaction pathways, more mild conditions, and less environmental load. Nevertheless, substrate scope is limited and the reducing strength of many metal reagents greatly surpasses what is possible with the best organic reductants.

可以通过仔细选择取代基，附加到母体结构的组来修改化合物的性质。在众多取代基中，氨基群体由于其强大的pi腐蚀特性，已成为需要更丰富电子母体结构的应用中使用的。我们最近证明，与普遍认为氨基群是氨基群是最重要的pi-donor取代基的相反，在这方面，亚米磷酸化取代基（R3P = n-）甚至更强。我们利用了该特性来准备最强大的中性有机电子供体，这些供体是均质减少剂的。在与金属基因试剂的互补性中，这种有机还原剂有望允许替代反应途径，更轻微的条件和较小的环境负荷。然而，底物范围有限，许多金属试剂的降低强度极大地超过了最佳的有机还原剂。
