Phosphorothioate-mercaptophosphonate rearrangement: Synthesis of new o-mercaptoaryl-and omercaptoheteroaryl phosphonates and their derivatives

New o-mercaptoaryl and o-mcrcaptohetcroaryl phosphonates and their derivatives were prepared via an ori/io-lithiation of O,O-diisopropyl S-aryl, 5-(2-pyridyl), S-(2-thienyl) and 5-(3-thienyl) phosphorothioates followed by a phosphonyl group S -> C.
