摘要：
The reaction of (hetero)aromatic aldehydes or cinnamaldehyde with di-/multi-ethers in the presence of Bu4NI and tert-butyl hydroperoxide generated corresponding alpha-acyloxy ethers. Reactions between (hetero)aromatic aldehydes or cyclohexanecarbaldehyde with arylalkyl ketones under similar conditions resulted in a-acyloxy ketones. Collectively, Bu4NI-catalyzed alpha-acyloxylation reactions exhibit a broad scope of substrates and a high compatibility with functional groups. (C) 2014 Elsevier Ltd. All rights reserved.
