2-Bromothiophene is obtained in high yields by adding a solution of bromine in 48% hydrobromic acid or a 35% aqueous solution of hydrogen peroxide to a mixture of thiophene, diethyl ether, and 48% hydrobromic acid. 2,5-Dibromothiophene is obtained in > 90% yields from thiophene and bromine in hydrobromic acid.
