Patent ID: 7078553

Claim:
A process for the preparation of a monoperoxy ester or monoperoxy carbonate having one of the following formulae: wherein R 1 and R 2 are independently selected from the group comprising hydrogen, C 1 –C 20 alkyl, C 3 –C 20 cycloalkyl, C 6 –C 20 aryl, C 7 –C 20 aralkyl, and C 7 –C 20 alkaryl, which groups may include linear or branched alkyl moieties; and each of R 1 and R 2 may optionally be substituted with one or more groups selected from hydroxy, alkoxy, linear or branched alkyl, aryloxy, halogen, ester, carboxy, nitrile, and amido, and R 3 is independently selected from the group comprising C 1 –C 20 alkyl, C 3 –C 20 cycloalkyl, C 6 –C 20 aryl, C 7 –C 20 aralkyl, and C 7 –C 20 alkaryl, which groups may include linear or branched alkyl moieties; and R 3 may optionally be substituted with one or more groups selected from hydroxy, alkoxy, linear or branched alkyl, aryloxy, halogen, ester, carboxy, nitrile, and amido, comprising the reaction of the corresponding ketone peroxide with the formula II: wherein R 1 and R 2 have the identified meaning, with an acid halogen or halogen formate of one of the following formulae: wherein R 3 has the identified meaning, in an inert two-phase solvent system comprising polar solvents.
