Phosphaalkenes with Inverse Electron Density

Abstract

This review gives an account of the syntheses, structures, and properties of phosphaalkenes R1P=CR2R3 with an inverse electron distribution at the P−C double bond (Pδ−Cδ+). The chemical reactivity of compounds of this type is novel and quite surprising compared to the chemistry of “classically polarized” phosphaalkenes (Pδ+Cδ−).
