Synthesis of 5-Cyano-2-Carbethoxythieno [2,3-b] thiophenyl-3, 4- Di- isothiocyanates and Its Utility IN Heterocyclic Synthesis Under Phase Transfer Catalytic Technique
Regarding to the importance of thieno[2,3-b]thiophens and isothiocyanaetes reactiveties in the physical, chemical and pharmaceutical fields, this study has been undertaken to prepare the target compound 5-cyano-2-carbethoxythieno[2,3-b] thiophenyl-3,4-diisothiocyanates via a safe method. The formed isothio cyanates derivative was reacted with aromatic amines, acid hydrazied and some active methylene groups, followed by cyclization reaction for the formed intermediates to give new ...

New Polymer Syntheses Part 60: A Facile Synthetic Route to Polyamides Based on Thieno[2,3-b]thiophene and Their Corrosion Inhibition Behavior
Polyamides containing thieno[2,3-_b_]thiophene moiety were prepared _via_ a simple polycondensation reaction of the diaminothieno[2,3-_b_]thiophene monomer 1A with different kinds of diacid chlorides (including oxalyl, adipoyl, sebacoyl, isophthaloyl, terephthaloyl, 4,4′-azodibenzoyl, 3,3′-azodibenzoyl, _p_-phenylene diacryloyl) in the presence of LiCl and NMP as a solvent through low-temperature solution polycondensation. The chemical structures of model compound and synthesized polyamides were confirmed by FTIR, nuclear ... Read more
