A simple and convenient method for iodination of so me hydroxylated aldehyde and ketones by iodine and iodic acid combination as iodinating rea gent under microwave irradiation and by conventional stirring method is reported. A combin ation of iodine and iodic acid has been found to be an efficient reagent for iodination of aromat ic aldehydes and ketones. For microwave assisted reactions, the reaction time were shortene d, but the yields were nearly same as those afforded by conventional method.
