The reaction of thiophene and 2,5-dimethylthiophene with isothiocyanates in the presence of aluminium chloride in nitromethane gave rise to the formation of the N-substituted carbothioamides of thiophene-2-carboxylic and 2,5-dimethyl-thiophene-3-carboxylic acid, respectively.Under similar conditions, 2-ethylthio-5-methylthiophene was attacked by the reagent at the carbon atom adjacent to the ethylthio group, whereas 2-phenyl-5-methylthiophene yielded a mixture of the 3- and 4-carbothioamides.
