Abstract

Described herein is method of making a halogenated partially fluorinated compound, comprising: (a) providing a compound having the following structure of formula (I): Rf—CF═CXY wherein X and Y are independently selected from F and Cl; wherein Rf is a fluorinated monovalent group comprising 1 to 10 carbon atoms; (b) contacting the compound with at least one of (i) an iodine or bromine containing salt in the presence of an acid; and (ii) aqueous solution of HZ wherein Z is selected from I and Br to form the halogenated partially fluorinated compound of the formula (II): R′f—CFH—CXYZ wherein X and Y are independently selected from F and Cl; Z is selected from I and Br; and R′f is a fluorinated monovalent group comprising 1 to 10 carbon atoms.
