Thermal chlorofluorination of propyne and propadiene II

Propyne and propadiene have been previously reported to readily undergo vapor phase catalyzed chlorofluorination at temperatures to 285 °C to form C3F4Cl4 mixtures that are primarily CFCl2–CF2–CFCl2. Continued fluorination at temperatures up to 485 °C produce the rearranged C3F6Cl2 isomers CF3–CCl2–CF3 and CF2Cl–CFCl–CF3.
