Thieno[2, 3-b]thiophene is prepared in a way similar to that previously described for the synthesis of thieno[3, 2-b]thiophene, the method being based on intramolecular condensation of methyl (3-formyl-2-thienylmercapto) acetate. The IR and PMR spectra of thieno[2, 3-b]-thiophene, 2-ethylthieno[2, 3-b] thiophene and 2-ethylthieno[3, 2-b]-thiophene are investigated.
