ResumoHydrogen peroxide reactions with ketones were studied by the nitroxide method. Fragmentation of ketones proceeded via hydrogen peroxide adducts. Radical substitution took place with boranes and plumbanes. Postulated radicals from photolysis of certain ketones have been trapped. Photolysis of aryliodides in the presence of t-nitrosobutane gave aromatic nitroxide radicals, the spectra of which were analyzed. Oxidative decarboxylation of carboxylic acid with thallic acetate proceeded via radicals. The splitting of the trichloromethyl nitroxide radicals is discussed. Some relationship between hyperfine Splittings and structure has been observed.
