3,5-Dinitroperoxybenzoic acid

Dinitroperoxybenzoic acid, (N02>2C6H3C000H. Mol. wt. 228.12, m.p. 113-115°. Caution All peroxyacids are potentially explosive when heated. Prepared by reaction of the carboxylic acid in methanesulfonic acid with 90% H2O2 at 50° (caution The reaction is exothermic at temperatures >53°) yield 93.5%. The reagent is stable for about a year at — 10°. [Pg.103]

The Baeyer-Villiger oxidation of aromatic ketones by peroxyacids is a widely applicable method for the synthesis of phenols . This oxidation can be carried out by organic peroxyacids such as peroxyacetic , trifluoroperoxyacetic , 4-nitro-and 3,5-dinitroperoxybenzoic acids . However, m-chloroperoxybenzoic acid is most frequently used. Hydrogen peroxide is sometimes used, but it works only in the presence of strong acids . [Pg.424]

During efforts towards the preparation of prostaglandins, optimum conditions for selective bridgehead migration have been established in the Baeyer-Villiger conversion of bicyclo[2,2,l]heptan-2-ones (107) into lactones (108). 3,5-Dinitroperoxybenzoic acid, a stable crystalline solid, may in some cases be preferable to peroxytrifluoroacetic acid for Baeyer-Villiger oxidation, as well as for olefin epoxidation. Various molybdenum peroxo-complexes catalyse the conversion of cyclic ketones into lactones by hydrogen peroxide. [Pg.97]
