摘要：
The transition-metal-free aerobic oxidation of benzylic alcohols is uniquely accelerated by a 1-butyl-3-methylimidazolium hexafluorophosphate (BMI-PF(6))/PhCF(3) biphasic system and Cs(2)CO(3) to afford the corresponding ketones in good yields. The reaction system is also applicable to an oxidative cross-esterification of primary benzyl alcohols with a higher aliphatic alcohol. (C) 2011 Elsevier Ltd. All rights reserved.
