2,4-Dimethylbromobenzene Chemical Properties,Uses,Production
Chemical Properties
Clear colourless to light yellow liquid
Uses
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.
Synthesis
108-38-3
583-70-0
General procedure for the synthesis of 2,4-dimethylbromobenzene from m-xylene: N-bromosuccinimide (NBS, 1.0 mmol) and Catalyst 1 (gold loading of 0.1 or 1 mol% of the substrate) were accurately weighed and added to a 10 mL sealed reaction vessel, followed by 1,2-dichloroethane (DCE, 2 mL) and m-xylene (1.0 mmol). The reaction mixture was stirred at a set temperature for a specified time. After completion of the reaction, the catalyst was separated using a magnet and the reaction solution was concentrated under reduced pressure and purified by column chromatography.
