Abstract
A PRELIMINARY study1 of the photochemical properties of the first fluorocarbon iodide, trifluoro-iodomethane, showed that a trifluoromethyl radical is produced the primary reactions of which parallel those of the hydrocarbon free radicals. A direct method thus became available for the preparation of perfluoroalkyl nitroso compounds, by irradiation of the iodide in the presence of nitric oxide and of mercury (to remove iodine), with the difference that the product would then be stable, in contrast to alkyl nitroso compounds, which dimerize, and re-arrange to form oximes2. (Ruff and Giese3 had previously reported as a by-product of the action of elementary fluorine on silver cyanide containing the oxide and nitrate as impurities, a 1 : 1 mixture of CF3NO and FCONF2, from which the former could not be separated. Some properties and reactions were recorded, not all of which agree with the present work, or with what one would expect of the compound perfluoroformamide.)
