AIBN/NaBr-promoted aerobic oxidation of benzylic alcohols via a radical process.

ABSTRACT

An economic and practical AIBN-initiated aerobic oxidation system of benzylic alcohols, hetero aryl alcohols and allyl alcohols was developed for the first time. Moderate to excellent yields were obtained with a broad substrate scope. Moreover, a proposed mechanism of a radical process was assumed and confirmed by the key intermediate detected.
