The paper describes the influence of a series of bis(arylimino)acenaphthenes (R-bian) and mono(arylimino)acenapthenones (R-mian) in the aerobic oxidation of cumene. The imines facilitate the decomposition of minor impurities of cumene hydroperoxide, thereby acting as catalysts for the oxidation of cumene. The relative reactivity of imines in the oxidation of cumene is correlated with the relative electron-withdrawing ability of the aryl functional groups of CF3-Ph>dpp, tmp. This is demonstrated by the reactivity of dpp-mian, tmp-mian and dpp-bian, tmp-bian<CF3-Ph-bian. A comparable interaction between R-bian and NHPI enhances the solubility of the radical catalyst in cumene and intensifies NHPI-catalyzed oxidation to attain 25–30 % conversion of cumene with dpp-bian and tmp-bian promoters. The reported results present a straightforward organocatalytic system based on the utilization of imines as catalysts and promoters.
