Due to a continuing interest in the area of new perfluoropolymer forming reactions, we investigated the reaction of para-bonded hexafluorobenzene148 and bis-(fluoroxy)difluoromethane. During the course of the study, we found that CF2(OF)2 decomposed under photolysis into intermediates in the presence of C̿C bonds at -40 °C in an inert perfluoropentane solvent. The suggested active intermediates are fluorine atoms, •OCF2O diradicals, fluoroxy radicals, and oxygen atoms in the presence of carbonyl fluoride, which was detected by IR in the gas phase. When the oxygen atom and fluorine atoms or •OCF2O• diradical were added to the para-bonded hexafluorobenzene, perfluorobicyclo[2.2.0]hexane oxides were formed. © 1979, American Chemical Society.
