Process for the production of fluorophosphonic acid compounds

Fluorophosphonic acid compounds are obtained by reacting a compound of the general formula HX, where X denotes -OR, -SR, -NHR or -NRR1 and R and R1 are similar or dissimilar aliphatic, aromatic or hydroaromatic radicals with phosphorous oxy-dichlorofluoride. In the preparation of esters the use of a...

Zusammenfassung:Fluorophosphonic acid compounds are obtained by reacting a compound of the general formula HX, where X denotes -OR, -SR, -NHR or -NRR1 and R and R1 are similar or dissimilar aliphatic, aromatic or hydroaromatic radicals with phosphorous oxy-dichlorofluoride. In the preparation of esters the use of a solvent and an organic base to take up the hydrogen chloride formed in optional. Dry ammonia may be passed through the reaction mixture to remove hydrogen chloride. Examples are given of the preparation of diethyl, diethyldithio, bis-dimethylamino, bis-(benzylamino), bis-(cyclohexylamino) and diiso propyl and dicyclohexyl fluorophosphonate. Specification 601,210 is referred to.
