Efficient oxidation of benzylic alcohols mediated by NBS/UHP in ionic liquid

Hyun Jung Park and Jong Chan Lee. Chung-Ang university, Seoul, South Korea

The oxidation of alcohols to carbonyl compounds has been recognized as a fundamental organic transformation in synthetic organic chemistry. Various methods have been developed for the oxidation of benzyl alcohols to the corresponding benzaldehyde or acetophenone. However, the majority of known methods commonly suffer from one or more disadvantages such as difficulty in manipulation, long reaction times, and utilization of toxic reagents. Therefore, it is still desirable to develop a new efficient oxidant with properties of high stability, low toxicity, and ready availability for the benzylic oxidations. Effective oxidation reactions of pri-, sec- alcohols into the corresponding the oxidation have been accomplished using N-bromsuccinimides and urea-hydrogen peroxide in [bmim]BF4 ionic liquid.
