一般說明
The photolysis products of dibromodifluoromethane were characterized by matrix isolation infrared and UV/Visible spectroscopy. Free radical addition of dibromodifluoromethane with fluoroolefins has been reported. Dibromodifluoromethane reacts with hydrocarbon olefins to yield 1,3-dibromo-1,1-difluoroalkene. Sulfinatodehalogenation reagent promoted addition reaction of difluorodibromomethane with alkenes, alkynes and cyclic enol ethers has been described.
應用
- Synthesis of 3‑Fluoropyrazoles via Radical-Polar Crossover Photoinduced Cyclization: This study highlights the use of dibromodifluoromethane (CF2Br2) for the synthesis of valuable difluorinated and monofluorinated compounds through a novel photoinduced cyclization process (MA Reed, ND Patil, Synfacts, 2023).

The photolysis products of dibromodifluoromethane (CF(2)Br(2)) were characterized by matrix isolation infrared and UV/Visible spectroscopy, supported by ab initio calculations. Photolysis at wavelengths of 240 and 266 nm of CF(2)Br(2):Ar samples (approximately 1:5000) held at approximately 5 K yielded iso-CF(2)Br(2)
