Abstract
A facile and convenient synthesis of some novel hydrazones, schiff's base and pyrazoles from thieno[2,3-b] thiophene derivatives 1 have been achieved in high yields assisted by microwave and classical methods. The structures of all the title compounds have been elucidated by elemental analysis, IR, MS, H-1-NMR and C-13-NMR. Generally, these findings represent a new class of sulfur and nitrogen moieties that should also be of interest as new materials.
