Vinyl bromide is the organobromine compound with the formula CH2=CHBr. Classified as a vinyl halide, it is a colorless gas at room temperature. It is used as a reagent and a comonomer.

Synthesis, reactions, and applications

It is produced from ethylene dibromide:

CH2Br−CH2Br → CH2=CHBr + HBr

CH2=CHBr is mainly consumted as a comonomer to confer fire retardant properties to acrylate polymers.[2]

Vinyl bromide reacts with magnesium to give the corresponding Grignard reagent CH2=CHMgBr.[3][4]

Safety precautions

Vinyl bromide is listed in List of IARC Group 2A carcinogens as a suspected human carcinogen.
