ABSTRACT:
Preparing O,O'-diesters of thiophosphoric acid, O-monoesters of thiophosphonic acid or thiophosphinic acids and their salts, from diesters of phosphorous acid, monoesters of phosphorous acids or phosphinous acids and sulphur in the presence of an aqueous solution of an auxiliary base. The solutions can be used in further syntheses or as extraction agent for cations.
