Abstract

The thermal decomposition of benzoyl peroxide in benzotrifluoride has been found to give negligible reaction with thc trifluoromethyl group but a 50% yield of a mixture of isomeric phenylbenzotrifluorides'(18yo o-, 40% m-, 42% p-). In the reactions of benzoyl, p- chlorobenzoyl and p-nitrobenzoyl peroxide with benzotrichloride, on ascending in electron- seeking character from the phenyl to the p-chlorophenyl to the p-nitrophenyl free radical,(a ...
