摘要
A novel and simple procedure for the construction of fully substituted thiophene-2,4-diamines using tertiary thioamides was developed. Thus, thioacetomorpholides undergo self-condensation to the corresponding 3,5-diarylthiophene-2,4-diamine derivatives in the presence of iodine and potassium carbonate in a suitable solvent and under mild conditions.
