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.
