with potassiumpermanganate and acetic acid, in which acetoxylation products were obtained in 74–96% yields. The same reaction was carried out with carboxylic acids other than acetic acid, which furnished corresponding acyloxy ketones with the same regioselectivity. For the first time, formyloxylation products were synthesized in a 61–85% yield by using formic acid. The potassiumpermanganate and acetic

A method for producing an α-acyloxycarbonyl compound of the present invention includes performing an intermolecular reaction between a carboxylic acid and a carbonyl compound selected from the group consisting of ketones, aldehydes, and esters, which have a hydrogen atom at the α-position, using a hydroperoxide as an oxidizer and an iodide salt as a catalyst precursor, thereby introducing an acyloxy group derived from the carboxylic acid into the α-position of the carbonyl compound.
