The mechanism of photodecomposition of phenyl benzoate in inert solvents at 242 and 282 nm


The mechanism of photodecomposition of phenyl benzoate solutions in Freon 113 (CCl_2FCF_2Cl), pure or doped with cyclohexane, was investigated by irradiating at 242 and 282 nm, with the specific goal of discovering the origin of phenol in this and related systems. It was found that the products of a short-chain reaction initiated by benzoyl radicals, rather than the solvent, provide the source of abstractable hydrogen atoms for phenoxyls, at variance with earlier conflicting reports. This view is confirmed by finding yields for ester disappearance larger than unity.
