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

The effect ofn-decylammonium chloride/n-decylamine mixed micelles on the rate of hydrolysis of aryl esters of acids of four-coordinate phosphorus was studied spectrophotometrically. The shape of the concentration curves is characteristic of the micellar catalysis reactions. The binding constants of the substrate, critical micelle concentrations, and the rate constants in the micellar phase were determined
