A simple and convenient method for iodination of some hydroxylated aldehyde and ketones by iodine and iodic acid combination as iodinating reagent under microwave irradiation and by conventional stirring method is reported. A combination of iodine and iodic acid has been found to be an efficient reagent for iodination of aromatic aldehydes and ketones. For microwave assisted reactions, the reaction time were shortened, but the yields were nearly same as those afforded by conventional method.
