Abstract
A study was made of the bromination of the complex of 2-cyanothiophene with AlCl3, which leads predominantly to the 4-bromo derivative. In the nitration of 2-cyanothiophene in H2SO4 and subsequent workup the nitrile group is converted to the carboxyl group, and consequently the reaction products are the 4- and 5-nitro derivatives of 2-thiophenecarboxylic acid.
