A process for producing a perfluorinated functional compound is disclosed, which comprises:
A. converting an at least partially hydrogenated alcohol into an at least partially hydrogenated fluoroformate compound;
B. reacting said at least partially hydrogenated fluoroformate compound with fluorine in the presence of at least one (per)haloolefin comprising at least one carbon-carbon double bond and having at least one fluorine or chlorine atom on either one of the carbon atoms of said double bond, to obtain a perfluorinated fluoroformate compound.
