The selective formation of e-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-R-quinolato Co(II1) complex formed in the initial fast step. An ionic mechanism of the reduction of the O-O bond in
The oxygenation of 4-(N-arylmethyleneamino)-2,6-di-t-butylphenols with Co(Salpr), a five coordinate Co(I1) Schiff base complex, in CH2C12 results in the regioselective hydroperoxylation at the imino carbon to give N-(1-aryl-1-hydroperoxymethyl)-3,5-di-tbutyl-R-benzoquinone mnoimines, which give excl
