Homolytic reactions of perfluoroaromatic compounds. Part I. Arylation of hexafluorobenzene

The reactions between hexafluorobenzene and a series of diaroyl peroxides have been shown to give 2,3,4,5,6-pentafluorobiphenyl and appropriately substituted derivatives. The significance of the yields of the biaryls obtained and the nature of the other reaction products are discussed, and a mechanism for the reaction is suggested tentatively.
