✦ Synopsis

The radical reactions of 2,6-di-t. butyl-1,4-benzoquinone with various thermally decomposing azocompounds and peroxides have been studied by ESR. On the basis of the ESR spectra of the intermediate radicals, the mechanism of the reaction is suggested. It was found that, while primary alkyl radicals from azocompounds add to the carbonyl oxygen, the peroxides, in the first step, oxidise one of the methyl group of the t. butyl group of the guinone. The intermediates are formed by addition of these species to the initial quinone molecule.
