摘要：

A combination of α‐electron‐withdrawing/‐releasing substituents (push‐pull substitution) at iminophosphanes considerably lengthen (shorten) the central PN bond as revealed by ab initio calculations on model geometries; they also stress the importance of the energy barrier to inversion at nitrogen.
