STUDY OF THE ELECTRON-TRANSFER INITIATED REACTION OF N,N-DICHLORO-5-IODO-3-OXA-OCTAFLUOROPENTANE SULFONYL AMIDE AND CARBOMETHOXYDIFLUOROMETHANE SULFONYL AZIDE WITH 2-METHYL-2-NITROSOPROPANE

The reactions of N,N-dichloro-5-iodo-3-oxa-octafluoropentane sulfonyl amide (1) and carbomethoxydifluoromethane sulfonyl azide (2) with 2-me thyl-2-nitrosopropane (3) have been studied by EPR spectroscopy. Our r esults suggest that these reactions are initiated by electron transfer (ET) between the perfluoroalkane sulfonyl compounds and the donor 3. The reaction of the dichloroamide 1 with 3 yields either one of two pr oducts, i.e., the unsymmetrical nitroxide 4 or the symmetrical nitroxi de 5, depending on the nature of the solvent and the amount of 1 used. Possible mechanistic paths are discussed.
