Bromobenzene

| Section8 = }}

Bromobenzenes are a group of halobenzenes formed in a substitution reaction between bromine and benzene with a hydrogen bromide biproduct. The name strictly refers to monobromobenzene, a benzene with a single bromine; however it can be used to refer to a benzene containing any number of bromine molecules. Bromobenzene is a clear pale yellow liquid.

Uses

Bromobenzene can be used to prepare the corresponding Grignard reagent, phenylmagnesium bromide. This can be used in a number of fashions, e.g. the reaction with carbon dioxide to prepare benzoic acid. Bromobenzene is used in the production of drugs.

Pharmacology

It is a toxic substance and can cause liver and nervous system damage if inhaled, ingested or absorbed through the skin.
