A FACILE METHOD TO SYNTHESIZE OF THIENO[2,3-B]THIOPHENE-3,4-DIAMINES

A new one-pot method has been described for the synthesis of thieno[2,3-b]thiophene- 3,4-diamines from the reaction of malononitrile, carbon disulfide, sodium carbonate and the chloroacetic acid derivatives in the H2O-EtOH environmentally friendly solvent system. The chemical structures of all compounds were characterized by 1H NMR, 13C NMR and FT‐IR spectrometry.
