Bromobenzene is an aryl bromide and the simplest of the bromobenzenes, consisting of a benzene ring substituted with one bromine atom. Its chemical formula is C 6 H 5 Br. It is a colourless liquid although older samples can appear yellow. It is a reagent in organic synthesis.
Benzyl bromide is used in organic synthesis for the introduction of the benzyl groups when the less expensive benzyl chloride is insufficiently reactive. [6] [7] Benzylations are often achieved in the presence of catalytic amounts of sodium iodide, which generates the more reactive benzyl iodide in situ. [3]
Bromobenzenes are a group of aryl bromides/halobenzenes consisting of one or more bromine atoms as substituents on a benzene core. They have the formula C 6 H 6–n Br n, where n = 1–6 is the number of bromine atoms. Depending on the number of bromine substituents, there may be several constitutional isomers possible.
In the first step, two bromine atoms are added to the methyl group of 4-bromotoluene by free radical bromination to form 4-bromobenzal bromide. In the second step, the dibrominated methyl group is hydrolyzed with calcium carbonate , then steam distilled to collect 4-bromobenzaldehyde.

Benzamide is an organic compound with the chemical formula of C 7 H 7 NO.It is the simplest amide derivative of benzoic acid.In powdered form, it appears as a white solid, while in crystalline form, it appears as colourless crystals. [5]
1,2,4,5-Tetrabromobenzene is an aryl bromide and a four-substituted bromobenzene with the formula C 6 H 2 Br 4. It is one of three isomers of tetrabromobenzene. The compound is a white solid. 1,2,4,5-Tetrabromobenzene is an important metabolite of the flame retardant hexabromobenzene. [1]
lic 6 h 4 ch 2 n(ch 3) 2 + e + → 2-ec 6 h 4 ch 2 n(ch 3) 2 Via these reactions, many derivatives are known with the formula 2-X-C 6 H 4 CH 2 N(CH 3 ) 2 (E = SR, PR 2 , etc.). The amine is basic and undergoes quaternization with alkyl halides (e.g. hexyl bromide ) to give quaternary ammonium salts: [ 4 ]
