Anomalous elimination of HCl from 2-chloro-1,1-difluoroethane. Likely involvement of a 1,2-FCl interchange mechanism
Dolbier Jr., William R.,Romelaer, Raphaele,Baker, J.Marshall
, p. 8075 - 8077 (2002)
A novel 1,2-FCl interchange mechanism is proposed to be involved in the unexpected thermal conversion of CH2ClCHF2 to 1,2-difluoroethylene.
Vibrationally excited populations from IR-multiphoton absorption. II. Infrared fluorescence measurements

Infrared emission spectra were obtained for 1,1,2-trifluoroethane (TFE) excited by infrared multiphoton absorption (1079.85 cm-1).The emission features show that the HF reaction product is formed in vibrational states up to about v = 3.Furthermore, emission attributed to F-CC-H was observed near 3320 cm-1, indicating that the difluoroethylene primary products of TFE decomposition undergo secondary photolysis; since the difluoroethylene products at room temperature do not absorb laser light, they must be formed vibrationally excited.The emission from the C-H stretch modes of TFE was readily identified near 2980 cm-1 and the emission intensity was obtained as a function of laser fluence.These data are in excellent agreement with predictions based on the theoretical expression for fluorescence intensity and the reconstructed populations determined by the Master Equation calculations described in the preceding paper.These results provide additional support for the accuracy of the reconstructed population distributions and for the theory relating infrared fluorescence intensity to total vibrational energy in polyatomic molecules.
Gas-phase kinetics of the self reactions of the radicals CH2F and CHF2
Beiderhase, Thomas,Hack, Walter,Hoyermann, Karlheinz,Olzmann, Matthias
, p. 625 - 641 (2000)
Fluorinated hydrocarbon radical-radical reactions in the gas phase have been studied at low pressure (0.5 ≤ p/mbar ≤ 2) and low temperature (253 ≤ T/K ≤ 333) using the discharge flow reactor molecular beam sampling mass spectrometry (MS) technique. Stable
METHOD FOR PRODUCING 1-CHLORO-1,2-DIFLUOROETHYLENE
-
Paragraph 0115, (2019/06/17)
The present invention provides a method for efficiently producing 1-chloro-1,2-difluoroethylene at low cost. Specifically, the present invention provides a method for producing 1-chloro-1,2-difluoroethylene, including the step of dehydrohalogenating chlorofluoroethane represented by formula (1) CFClX1—CHFX2 wherein X1 and X2 are different from each other and represent H, F, or Cl; and either X1 or X2 is H.
Copper-Catalyzed Difluoromethylation of Aryl Iodides with (Difluoromethyl)zinc Reagent
Serizawa, Hiroki,Ishii, Koki,Aikawa, Kohsuke,Mikami, Koichi
supporting information, p. 3686 - 3689 (2016/08/16)
The combination of difluoroiodomethane and zinc dust or diethylzinc can readily lead to (difluoromethyl)zinc reagents. Therefore, the first copper-catalyzed difluoromethylation of aryl iodides with the zinc reagents is accomplished to afford the difluorom
