Iodine, either alone or in combination with DDQ, has been found to serve as a very efficient reagent for the conversion of 'disarmed' glycosyl halides into simple 1,2-trans-glycosides. This reagent system represents a practical alternative to traditional heavy metal promoters in glycoside synthesis.
