Reactions with hydrazonoyl halides XXIX: Synthesis of some new 1,2,4-triazolo[4,3-a]benzimidazole,thiazolo[3,2-a]benzimidazole,and unsymmetrical azine derivatives
Triazolo[4,3-a]benzimidazole, thiazolo[3,2-a]benzimidazole, and unsymmetrical azines, were synthesized via reactions of C-thiazol-5-oyl-N-phenylhydrazonoyl bromide with each of 2-(methylthio)benzimidazole, benzimidazoline-2-thione, and alkyl carbodithioate, respectively.
