Synthesis and Characterization of Polyazothiazole and Polyacetyltetrazine from Novel Bis-Ketohydrazonoyl Dichlorides

Abstract

The present work describes the preparation and characterization of new polyazothiazole and polyacetyltrazine polymers in good yields from new bis-(α-ketohydrazonoyl) dichlorides. Synthesis of the new polyazothiazole proceeds through the reaction of bis-(α-ketohydrazonoyl) dichlorides with 1,4-phenylene[bis(carbothioamide)] in a basic medium to afford novel polyazothiazole derivatives. Additionally, the self-polymerization reaction to synthesize polydiacetyltetrazine derivatives based on bis-(α-ketohydrazonoyl) dichlorides is described. The new polyazothiazole and polyacetyltetrazine derivatives were characterized using spectral and thermal techniques.
