The selective formation of p-quinols in the Co(Salpr)-catalyzed oxygenation of 4-alkyl-2,6-di-t-butylphenols in MeOH has been found to involve the rate determining reduction of peroxy-p-quinolato Co(III) complex formed in the initial fast step.An ionic me

The title peroxy esters 1, when deprotonated with t-BuOK in DMF to the corresponding phenolate anions, decompose even at -78 deg C to give compounds 2-10.These compounds result undoubtedly from homolysis of the peroxy bond in 1, indicating that the generation of a carbanion at the α-position of the acyl group in peroxy esters (via resonance in the present case) induces ready homolysis of the peroxy bond.The oxidation of 1 with one-electron oxidizing agents gives rise to the corresponding phenoxy radicals, which also induce homolysis of the peroxy bond.
