Water determines the products: an unexpected Brønsted acid-catalyzed PO–R cleavage of P(<scp>iii</scp>) esters selectively producing P(O)–H and P(O)–R compounds

Abstract

Water is unexpectedly found to determine a TfOH-catalyzed C–O cleavage reaction of trialkyl phosphites to produce H-phosphonates or alkylphosphonates selectively.
