Disclosed is a process for the preparation of .alpha.-iodocarbonyl compounds such as .alpha.-iodocarboxylic acid anhydrides and .alpha.-iodoketones by the reaction of a carboxylic anhydride with molecular iodine. Hydrolysis of the .alpha.-iodocarboxylic acid anhydrides gives the corresponding .alpha.-iodocarboxylic acids.
