The acylation of alkyl hydroperoxides with acid chlorides under the phase transfer conditions (PTC) is studied. An evident catalytic effect was observed. This reaction can be considered as a convenient method for the synthesis of organic peresters.
DECOMPOSITION HETEROLITIQUE DE PERCARBONATES DE O,O-METHYL-1 PHENYL-1 ETHYLE ET O-ALKYLE OU O-VINYLE EN SOLUTION

O,O-α-cumyl O-ethyl, O-vinyl and O-isopropenyl peroxycarbonates (percarbonates) have been prepared from the corresponding chloroformates.Their decompositions have been studied in triisopropylbenzene and di-n-butyl phtalate as solvents; in both cases the main process was the heterolysis of the peroxydic bond (Criegee rearrangement) which gave 2-phenoxy propene.Kinetic studies have been performed using Differential Scanning Microcalorimetry; they have shown that the decomposition of O,O-α-cumyl O-ethyl percarbonate is faster in di-butyl phtalate than in triisopropylbenzene and that the rate constants depend on the initial concentrations of the solutions.From both chemical and kinetic data it has been concluded that the studied percarbonates cannot act as free radical initiators even in non polar media.
