✦ Synopsis

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 exclusively the corresponding amides and 2,6-di-t-butyl-e-benzoquinone in an aerobic solution of KOH in 90% EtOH.
