Rate constants for reactions of dichloride anion radical with nucleosides, nucleotides, and polynucleotides were determined in neutral aqueous solutions of potassium chloride by the conventional flash photolysis. The reactivities of these compounds toward the anion radical are in the order: bases>nucleosides>nucleotides>polynucleotides. This trend is similar to that observed with the corresponding reactions with hydroxyl radical. A comparison of the reactivities of nucleosides, nucleotides, and polynucleotides toward dichloride anion radical with those toward hydroxyl radical has revealed that the reactivities of these compounds are governed mainly by their base moiety. This trend in the reactivities is discussed in terms of steric effect.
