General description
2-Bromo-3-methylthiophene is formed (approx. 90%) by bromination of 3-methyl thiophene with N-bromosuccinimide in the absence of benzoyl peroxide.
Application
2-Bromo-3-methylthiophene was used in the preparation of poly(3,3′′′-dimethyl-(2,2′:5′,2′:5′,2′′′)tetrathiophene)). It was also used in the preparation of 2-bromo-3-(bromomethyl)thiophene, lachrymatory compound.
