Synthesis of peroxydicarbonates containing alkyl-aromatic fragments and investigation of their properties
The reaction of alkyl-substituted benzyl- and naphthylmethyl-chloroformates with Na2O2 or cyclohexyloxyperoxycarbonic acid at 0-5 deg C leads to symmetric and asymmetric peroxydicarbonates.Investigation of the thermolysis kinetics of the peroxides at 50-70 deg C showed that the structure of the organic fragment influences the rate of homolysis of the O-O bond to a great extent.This is characteristic in particular for compounds containing substituents in the ortho-position, where the presence of methyl radicals leads to a decrease in the contribution of the induced dissociation to the overall rate of homolysis of the peroxides obtained
