CONVENIENT METHODS FOR THE SYNTHESIS OF NOVEL THIADIAZOLES AND POLYTHIADIAZOLES

摘要

In this study, the novel thiadiazoles were formed via the reaction of hydrazonoyl halides with methyl 2-(adamantan-2-ylidene)hydrazinecarbodithioate. Also, the reaction of 2,5-dihydraziny1-1,3,4-thiadiazoles with 2-adamantanone or acetylferrocene produced the 2,5-bis(2-(adamantan-2-ylidene)hydraziny1)1,3,4-thiadiazole or 2,5-bis(2-(1-(ferrocenylidene)hydraziny1)-1,3,4-thiadiazole, respectively. Analogously, treatment of terephthalaldehyde with 2,5-dihydrazinyl-1,3,4-thiadi azole afforded new poly(benzylidenehydraziny1-1,3,4-thiadiazole). Finally, the reaction of bishydrazonoyl halides with 2,5-dihydrazinyl-1,3,4-thiadiazole afforded new poly(1,3,4-thiadiazolo[2,3-c][1,2,4]triazine). The synthetic structures for the final products are suggested and discussed. The compound structures of the products were recognized by different spectroscopic analyses.
