The reaction of (hetero)aromatic aldehydes or cinnamaldehyde with di-/multi-ethers in the presence of Bu4NI and tert-butylhydroperoxide generated corresponding α-acyloxy ethers. Reactions between (hetero)aromatic aldehydes or cyclohexanecarbaldehyde with arylalkyl ketones under similar conditions resulted in α-acyloxy ketones. Collectively, Bu4NI-catalyzed α-acyloxylation reactions exhibit a broad
