Peroxysulfur compounds

Compared with peroxysulfur compounds, very few peroxyphosphorus compounds are reported. Phosphorus peroxide derivatives have been postulated as possible intermediates in certain biological transformations, although they have never been isolated in such systems . Monoperoxyphosphonic acid can be prepared in situ and applied for some common oxidation reactions ". Only one example of phosphorus peroxide, i.e. bis(phenylphosphinyl) peroxide, has been studied . It is believed that when trivalent phosphorus compounds are allowed to react with ozone and a source of singlet oxygen, phosphorus ozonides 54 are obtained (equation 89). ... 

Calvert and McQuigg suggest that yet unknown radicals, such as 0CH20 or those derived from it, formed in the 03-olefin-air mixtures may oxidize S02 in the homogeneous reaction. It is known that OH and H02 radicals combine rapidly with S02. The addition products may eventually be transformed into sulfuric acid, peroxysulfuric acid, sulfates, and nitrates in a polluted atmosphere probably in a liquid phase of aerosol particles, although the detailed steps are still unknown. Finlayson and Pitts (357) believe that the oxidation of aromatic compounds by such species as OH, H02, 03, and 0(3P) may also be significant for the formation of organic aerosol. 

Desulfuration.1 The reaction of K02 with o-nitrobenzenesulfonyl chloride results in a peroxysulfur reagent that converts thioureas, thioamides, and thiocar-bamates in CH3CN at -30° into the corresponding carbonyl compounds. Example ...
