Reactions between 2,6-dialkyl-l,4-benzoquinones and various free radicals have been studied by ESR spectroscopy. The stable intermediates were identified on the basis of their spectra. It has been established that cyanoisopropyl, polystyryl and poly-(ct-methylstyryl) radicals attack at the oxygen at

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
