In order to obtain insight into the selectivity of Mg2+ at the site of bond cleavage of P–O and S–O of the P–O–Slinkage, metal ion-promoted alcoholyses of phenyl phosphatosulfate were studied. Mg2+ quantitatively promoted P–O bond cleavage in the methanolysis, but mixed cleavage of the P–O bond, which occurred partly due to hydrolysis by trace water and the S–O bond in the reaction of ethanol, 1-
