Abstract
THE primary act in the photolysis of acetone at room temperature has been shown by a number of workers to be the production of an acetyl and a methyl radical1. It is believed that the photolysis of hexafluoroacetone is a simpler process in which only trifluoromethyl radicals and carbon monoxide are formed2. Hexafluoroacetone is thus an unambiguous photochemical source of trifluoromethyl radicals, and the close structural similarity of 1 : 3-dichlorotetra-fluoroacetone has prompted an investigation into its suitability as a source of difluorochloromethyl radicals.
