and poly-saccharide derivatives. It is shown that ( 1 ) unsubstituted d -glucopyranosides undergo selective, primary iodination without unwanted side-reactions; ( 2 ) primary iodination of d -galactopyranosides is accompanied by 3,6-anhydride formation, so that the desired reaction is only possible with protection of secondary hydroxyl groups; and ( 3 ) the extent of iodination in substrates of higher
