Peroxysuccinic acid

Oxidation. Succinic acid reacts with hydrogen peroxide, giving different products that depend on the experimental conditions peroxysuccinic acid [2279-96-1] (CH2COOOH)2, oxosuccinic acid [328-42-7] (oxaloacetic acid) malonic acid [141-82-2] or a mixture of acetaldehyde, malonic acid, and make acid [6915-15-7]. Succinic anhydride in dimethylformamide (DMF) with H2O2 gives monoperoxysuccinic acid [3504-13-0], HOOCCH2CH2COOOH, mp 107°C (70).

In References 32 and 33 we find the liquid phase enthalpies of formation of the methyl and allyl esters of the OO-fert-butyl peroxyfumaric and peroxysuccinic acids. The difference between the enthalpies of formation of each fumarate and succinate pair of peresters is the enthalpy of hydrogenation. The enthalpy of hydrogenation to the succinate of the methyl fumarate is —131.4 3.6 kJmol", and of the allyl fumarate is... 

Despite the attractiveness of this proposal, peroxy acids such as (83) and (84) are unlikely to function as the critical oxenoid intermediates in the enzymic process. Peroxysuccinic acid has been added to both the proline-4-hydroxylase and thymidine-2 -hydroxylase systems, but it does not replace the requirement for oxygen and 0x0 glutarate 253). Furthermore, it is unlikely that such a peroxy acid would have sufficient reactivity to carry out the specified hydroxylation. Moreover, we have prepared the peroxy acid (84) and have found that it too is incapable of performing the required intramolecular oxene transfer. No products like (85), (86) or (87) are formed 287). 

Various (2-oxoalkyl)cyclopropanes have been oxidized by cleavage of the bond between the carbonyl group and the carbon atom a to the cyclopropane ring to give cyclopropylmethyl esters. Most of these transformations have been performed using peracids such as peracetic acid, ° 3-chloroperoxybenzoic and peroxysuccinic...
