Synthesis of organophosphorus compounds based on the reaction of elemental phosphorus with proton-donor reagents

Abstract

Reaction of elemental (white) phosphorus with proton-donor reagents has been studied. The following organophosphorus compounds containing P-O and P-S bonds have been synthesized: metal hypophosphites and phosphites, and ammonium salts of O,O′-diesters of dithiophosphoric, S,S′-diphenyldithiophosphoric, S,S′-dialkyltetrathiophosphoric, O,O′-alkylidenedithiophosphoric acids, and octathiotetraphosphetane. The reaction products include highly efficient inhibitors of steel corrosion with carbonic acid and hydrogen sulfide as well as compounds showing fungicide, anticancer, and anti-inflammatory activity.
