Description

General description

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.

Packaging

25 mL in glass bottle

Other Notes

Reagent for the Wittig olefination of carbonyl compounds to difluoromethylene and fluoromethylene derivatives; Precursor of difluorocarbene
