Vinyl bromide

Vinyl bromide is the organobromine compound with the formula CH2\dCHBr. 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\sCH2Br -> CH2\dCHBr  +  HBr

CH2\dCHBr is mainly consumted as a comonomer to confer fire retardant properties to acrylate polymers.

Vinyl bromide reacts with magnesium to give the corresponding Grignard reagent CH2\dCHMgBr.

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