The principal radical reaction of carbohydrate azides is reduction to tin-substituted amines by reaction with tri-n-butyltin hydride. Products from this reaction are isolated either as free amines or amine derivatives. Three radical reactions for synthesis of carbohydrate azides are known. One of these involves the addition of a carbohydrate radical to ethanesulfonyl azide. A second is the azidonitration that takes place when an azide radical adds to a glycal in the presence of ammonium cerium(IV) nitrate. Finally, reaction of a glycal with an azide radical and diphenyldiselenide, results in azidophenylselenylation.
