| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔfH°gas | -75. ± 50. | kJ/mol | EIAE | Heni and Illenberger, 1986 | From F2C=CHF |
| ΔfH°gas | <14.6 | kJ/mol | IMRB | Dawson and Jennings, 1976 | O- + CH2=CF2 ->. G3MP2B3 calculations indicate a HOF(A-) of -22 kcal/mol. |
| ΔfH°gas | -649. ± 59. | kJ/mol | EIAE | Harland and Thynne, 1975 | From CF3CHO. G3MP2B3 calculations indicate an EA of ca. 2.3 eV, and HOF(A-) of -22 kcal/mol. |
