Phosphorus compounds having at least one chlorine, bromine or iodine bonded directly to phosphorus are transhalogenated with fluorine by reaction with a fluoride salt, e.g., KF or ammonium fluoride, in the presence of a hydrogen halide salt of a pyridine-type nitrogen base, e.g., pyridine hydrochloride.
Phosphorus compounds having at least one chlorine, bromine or iodine bonded directly to phosphorus are transhalogenated with fluorine by reaction with a hydrogen fluoride salt of a pyridine-type nitrogen base, e.g., pyridine hydrofluoride in an inert solvent.

Phosphorus compounds having at least one chlorine, bromine or iodine bonded directly to phosphorus are transhalogenated with fluorine by reaction with anhydrous hydrogen fluoride in an inert solvent in a manner such that said anhydrous hydrogen fluoride is added to said phosphorus compound at a rate such that said anhydrous hydrogen fluoride reacts with said phosphorus compound without the accumulation of an amount of unreacted anhydrous hydrogen fluoride which is sufficient to cause substantial decomposition of the desired fluorophosphorus product.
