Metal Ion Dependent Site Selective Cleavage of P-O-S Linkage in the Methanolysis of Phenyl Phosphatosulfate

Article abstract of DOI:10.1246/bcsj.64.1235

Effects of various metal ions on the methanolysis of phenyl phosphatosulfate having P-O-S linkage were investigated.Metal ions examined were found to be divided into two different groups in the manner of cleavage of P-O-S linkage: Mg2+, Cr3+, Cu2+, Mn2+, and Ca2+ with larger ionic radii catalyzed the selective P-O bond cleavage, while Be2+, Al3+, Fe2+, And Zn2+ with smaller ionic radii promoted the selective S-O bond cleavage.Such selectivity was discussed in terms of the difference in the mechanism of P-O and S-O bond cleavage.
