Goloverda, V. Khizhnyi, V. Pokhodenko] The kinetics of the reaction of 2,4,6-tri-tert-butylphenoxyl radical with 1,4-benzoquinones was investigated. The composition and structure of the resulting products were established. A reaction mechanism is proposed in which transfer of one electron from phenoxyl to quinone in the initial step followed by rearrangement of the ion-radical pair to an electron-neutral free radical, recombination of which with the starting phenoxyl leads to formation of bis-cyclohexadiene compounds of the corresponding hydroquinones. The reaction rate is determined basically by the electronic influence of the substituents in the quinone, and the possibility of the formation of the final bis-cyclohexadienone is dependent on the steric accessibility of the oxygen in the quinone.
