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.

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. The Grignard reaction is an organometallic chemical reaction involving alkyl- or aryl-magnesium halides, also called Grignard reagents, with electrophiles. ... Phenylmagnesium bromide, with the simplified formula C6H5MgBr, is a a magnesium-containing organometallic compound. ...


Pharmacology

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

Synthesis of Bromobenzene (611 words)
Run off the bromobenzene, shake it again with water to ensure absence of alkali, and then dry with calcium chloride for 20-30 minutes.
Almost pure bromobenzene is thus obtained, usually of bp 154- 156°C if distilled directly, and of bp 155-156°C if a column is used.
Bromobenzene is a colourless liquid of bp 156°C, and d 1.50: it has a faint agreeable odour.
NTP: ChemIDPlus/HSDB 95-46-5 Toxicity (1017 words)
The toxicity of these bromobenzene derivatives was assessed using serum glutamate-pyruvate transaminase and histology for the in vivo experiments and protein synthesis and intracellular K+ and LDH for the in vitro liver slice experiments.
A series of ortho-substituted bromobenzene derivatives with widely differing hepatotoxicities were investigated for their tendency to undergo oxidative metabolism and protein covalent binding in the presence of rat liver microsomes in vitro.
Hepatocytes were incubated with bromobenzene, o-bromotoluene, o-bromobenzotrifluoride, o-bromobenzonitrile, o-bromoethylbenzene, o-dibromobenzene, or o-bromoanisole, at concentrations from O to 4.0 millimoles for 2 to 4 hours.
