Synthesis
It is made by reacting phosphorus pentachloride with potassium monofluorophosphate:[2]
- K2PO3F + 2PCl5 → POFCl2 + 2POCl3 + 2KCl
Reactions
The reaction with two equivalents of cyclohexanol yields the nerve agent dicyclohexyl phosphorofluoridate.[3][4]
The same reaction with isopropanol instead of cyclohexanol yields the nerve agent diisopropyl fluorophosphate.[5]
Two equivalents of sodium azide can replace the chlorine atoms with azide groups. Silver cyanate can replace them with cyanate groups.[6] Hexamethyldisiloxane can replace one of the two chlorine atoms with a trimethylsilyl ether.[7]
