The Uses of 2,4-Dimethylbromobenzene

4-Bromo-m-xylene is synthesized by the bromination of alkylbenzene substrates by N-bromosuccinimide.

General Description

Gold-catalyzed coupling reaction of pyrazine with 1-bromo-2,4-dimethylbenzene has been reported. 1-Bromo-2,4-dimethylbenzene reacts with Mg and DMF, followed by the reaction with I₂ and aq.NH₃ to afford the corresponding aromatic nitrile.
