Procedure

Typical compounds conforming to the above general formula are CH3Cl, CH2Cl2, CHCl3, CCl4, CH3F, CH2F2, CHF2Cl, and the like. Addition of such compounds to hexafluoropropene thermally is described in J. Fluorine Chemistry 1982, 21, 253-259. For example, CH2Cl2 addition to CF3CF═CF2 at 280° C. is reported to give 85% yield of CHCl2CF2CHFCF3.
