Abstract:	The oxygenation of 4-(N-arylmethyleneamino)-2,6-di- $t$ -butylphenols with Co(Salpr), a five coordinate Co(II0 Schiff base complex, in CH₂Cl₂ results in the regioselective hydroperoxylation at the imino carbon to give N-(l-aryl-l-hydroperoxymethyl)-3,5-di- $t$ -butyl- $p$ -benzoquinone monoimines, which give exclusively the corresponding amides and 2,6-di- $t$ -butyl- $p$ -benzoquinone in an aerobic solution of KOH in 90% EtOH.
