Synthesis and reactions of some new heterocyclic compounds containing a thieno[2,3-b]thiophene e.g., bis-thieno[2,3-b]thiophene derivatives 3a-d, 6 and 7 are described. The structures of all newly synthesized compounds have been elucidated by 1H, 13C NMR, GCMS and IR spectrometry. These compounds represent a new class of nitrogen and sulfur containing heterocycles that should also be of interest as new materials.
