Bromination peroxy acid oxidation

Fluoro-2.2-dinitroethyl)aniine is not affected by hydrogen peroxide in aqueous or methanolic solution, even in the presence of transition metal catalysts.218 On the other hand, it is oxidized by 3-chloroperoxybenzoic acid to the corresponding hydroxylamine 8, which on further oxidation by a second equivalent of the peroxy acid or bromine gives an oxime (vide infra).118...

Conjugated dienes (and compounds that behave like conjugated dienes in the Diels-Alder reaction) react with singlet oxygen to form cyclic peroxides as if molecular oxygen acted as a dienophile. The yields of the peroxides, prepared by photochemical oxidation [13, 55] or by chemical oxidations with hydrogen peroxide and sodium hypochlorite, alkaline hydrogen peroxide and bromine, alkaline salts of peroxy acids [14, 26], or the ozonide of triphenyl phosphite [29], are comparable. 

Oxidation of an aldehyde group to a carboxyl group has often been used for identification of the compounds. As far as can be judged from the results, such oxidations, using chromium trioxide/acetic acid, bromine-water, - peroxy acids, - or chlorite, have not been accompanied by any important side-reactions. Hypoiodite titration, using the iodine in sodium bicarbonate-sodium carbonate procedure, has sometimes been used, giving almost stoichiometric aldehyde determinations. - - Reduction by the Meerwein-Ponndorf reaction, with borohydride - - ... 

Sulfones are valuable intermediates for the synthesis of chemically and biologically useful molecules. Traditionally, they are prepared by oxidation of sulfides with nitric acid, KMnO, MnO, NaClO, m-chloroperbenzoic acid, sodium metaperiodate, bromine, dinitrogen tetraoxide, oxaziri-dine, benzeneseleninic peracid, tert-butyl hydroperoxide, sulfinyl peroxy compounds, iodosobenzene diacetate and 4-methylmorpholine N-oxide/ osmium tetroxide.
