Abstract: The synthetic utility of 3,3’-(3,4-dimethylthieno[2,3-b]thiophene-2,5-diyl)bis (3-oxopropanenitrile) (1) in the synthesis of some novel bis-[1,3,4-thiadiazole] 6a–g and bis-thiazole 10 and 13 derivatives with thieno[2,3-b]thiophene moiety is reported. Antimicrobial evaluation of some selected examples from the synthesized products was carried out and showed promising results.

Keywords: thieno[2,3-b]thiophene; nucleophilic addition; hydrazonoyl halides; bis-thiadiazoles; bis-thiazoles; antimicrobial activity
