According to quantum chemical theory, structural changes in the PN double bond of iminophosphanes are strongly influenced by the electronic properties of ?-push-pull substituents.This concept is strongly operative in oxy-substituted iminophosphanes, RO-P=N-Mes*, 2a-g, (R = silyl, organyl, and organosulfonyloxy; Mes* = 2,4,6-tBu3C6H2), which are synthesized by nucleophilic substitution of the chloro(aryl)iminophosphane 1 and structurally elucidated.The PO bond lengths vary from 1.585 (R = SiMe3) to 1.923 pm (R = CF3SO2) indicating spontaneous PO bond dissociation in the latter.Key words: oxy-substituted iminophosphanes / molecular structures / ab initio calculations
