spontaneous hydrolysis of tris‐2‐pyridyl phosphate (TPP) is explained by the activating effects of the non‐leaving (“spectator”) groups on POAr cleavage, and not by intramolecular catalysis. Previous work on phosphate‐transfer reactions has concentrated on the contributions to reactivity of the nucleophile and the leavinggroup, but our results make clear that the effects of the non‐leavinggroups on phosphorus
