The hydrolytic reactions of diribonucleoside 3',3'-monophosphates have been followed by RP HPLC over a wide pH-range at 363.2 K. The mechanisms of the reactions are discussed, particularly focusing on the possible stabilization of phosphorane intermediate and/or transition state via an intramolecular hydrogen bonding by the 2'-hydroxyl and 2'-amino group.
