The rates of the acid-catalyzed hydrolysis of phenyl phosphatosulfate (PPS) have been found to be highly dependent on the water content in the mixed solvent of acetonitrile–water. A remarkable rate acceleration was observed with a rate maximum near the 1 : 1 ratio of PPS and metal ion, and with a solvent with a low water content. Under such conditions, the site of the cleavage of the P–O–S linkage was observed to be predominantly the S–O bond.
