Abstract

Reactions between 2,6-dialkyl-1,4-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-(α-methylstyryl) radicals attack at the oxygen atom of the quinone, whereas the radicals formed in the thermal decomposition of peroxides (benzoyl and acetyl) attack the CC double bond in the quinone ring. A mechanism is proposed for the latter process.
