## Abstract Analysis of the proton NMR spectra of Pr^1^PCINMe~2~ indicates magnetic non‐equivalence of the methyl groups due to the adjacent asymmetric phosphorus atom. High temperatures, or the addition of chloride ion, induce an exchange reaction with inversion of configuration at phosphorus. The

Abstract
The preparation of 1,1‐difluoro‐3,7‐di‐tert‐butyl‐2,8‐dioxa‐1‐phosphabicyclo[3.3.0]octa‐3,6‐diene (Dit‐BuADPO·F~2~)from hexafluoropropylene oxide (HFPO) and 3,7‐di‐tert‐butyl‐2,8‐dioxa‐1‐phosphabicyclo[3.3.0]octa‐2,4,6‐triene (DitBuADPO) is described. The solid state structure of DitBuADPO·F~2~ shows an unusual square pyramidal geometry. The structural and spectroscopic properties of DitBuADPO·F~2~ are compared with other oxidized derivatives of DitBuADPO that contain 5‐coordinate phosphorus.
