Monoperoxycarbonic acid

An example of an alkyl monoperoxycarbonic acid, 0-ben2yl monoperoxycarbonic acid [52123-51 -0] was prepared ia aqueous methanol solution by basic perhydrolysis of diben2yl peroxydicarbonate [2144-45-8] and subsequendy isolated ia 97% purity. It has been used as an epoxidi2iag agent (185) ...

Treatment of ethyl 2,7-di-/ert-butylthiepin-4-carboxylate (24) with 3-chloroperoxybenzoic acid at — 78 °C results in the benzene derivative 25 only, and no sulfur-oxidized products 80 however, the stable 2,7-di-ter/-butylthiepin (26) can be oxidized with 0-benzyl 00-hydrogen monoper-oxycarbonate at — 78 °C to give the corresponding S-oxide 27, which was monitored by HNMR spectroscopy at — 40°C. At —15 C, sulfoxide 27 was converted, via extrusion of sulfur monoxide, with a half-life of 5.5 hours to the benzene derivative 28.87 The oxidation reaction of 26 with excess of the monoperoxycarbonate did not proceed to the S,S-dioxide, even though the parent thiepin 1,1-dioxide is known to be stable at room temperature.15... 

Dialkyl peroxydicarbonates (17) are produced by reaction of alkyl chlo-roformates with sodium peroxide. OO-Acyl O-alkyl monoperoxycarbon-ates i 8 i are obtained from tine reaction of alky] chloroformates with perox-ycarbnxylic acids in the presence of a hase. Symmetrical di (organosulfonyl) peroxides (20, R = R2l) have been prepared by the reaction of organosul-fonyl chlorides with sodium peroxide or hydrogen peroxide in the presence of a base. Acyl organosullbnyl peroxides (19) are prepared from Ihe, organosulfonyl chlorides and a metal salt of a peroxycarboxylic acid. Acetyl cyclohexanesulfonyl peroxide has been produced commercially by the sulfoxidation of cyclohexane. QjH. in the presence of acetic anhydride.
