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]
[3] Bromobenzene is used to introduce a phenyl group into other compounds. One method involves its conversion to the Grignard reagent, phenylmagnesium bromide. This reagent can be used, e.g. in the reaction with carbon dioxide to prepare benzoic acid. [4] Other methods involve palladium-catalyzed coupling reactions, such as the Suzuki reaction.
Halogenation with thionyl chloride gave 4-Bromo-3,5-dimethoxybenzoyl chloride [56518-43-5] (6). Rosenmund reduction gave 4-Bromo-3,5-dimethoxybenzaldehyde [31558-40-4] (7). {Alternatively DIBAL meant that FGI from ester to aldehyde was accomplished in only 1 step}.
4-Bromobenzaldehyde, or p-bromobenzaldehyde, is an organobromine compound with the formula BrC 6 H 4 CHO. It is one of three isomers of bromobenzaldehyde . [ 3 ] It displays reactivity characteristic of benzaldehyde and an aryl bromide .
Bromobenzenes may be carboxylated into carboxylic acids using carbon monoxide.The reaction takes place in a two-phase mixture of p-xylene and water as solvent, in the presence of catalytic PdCl
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 ]

4-Bromoanisole is the organobromine compound with the formula CH 3 OC 6 H 4 Br. It is colorless liquid with a pleasant smell similar to that of anise seed. It is one of three isomers of bromoanisole, the others being 3-bromoanisole and 2-bromoanisole. It is the precursor to many 4-anisyl derivatives.
