| Abstract: | Four benzothiazolylhydrazohes and four azo bisheterocyclic compounds were synthesized. 2-Aminobenzothiazole was diazotized and coupled with reactive methylene compounds to form benzothiazolylhydrazones (1a-d),then (1) we.re reactedwith hydrazine hydrate in refluxing ethanol to form 2-benzothiazolylazo-3, 5-disubstituted pyrazoles (2a-d),and their analytical application were preliminarily studied. |
