Abstract

Abstract: The hydrolysis rates of phosphonosulfates having a neighboring 2-pyridyl group, 2- pyridyl-(1) and 2-pyridylmethylphosphonosulfate (2), have been compared with those of the corresponding phenyl-(3) and benzylphosphonosulfate (4) in a pH range of 1-9. All of the esters were found to undergo the acid-catalyzed reaction via the selective S-0 bond cleavage. Under neutral pH conditions, the PO bond was selectively cleaved in the ...
