Abstract
Triazolo[4,3-a]benzimidazole, unsymmetrical azine containing pyrazole moiety were synthesised via reactions of C-pyrazolôyl-N-p-chlorophenylhydrazonoyl bromide with each 2-(methylthio)benzimidazole and carbodithioates, respectively. Newly synthesised compounds were confirmed on the basis of elemental analysis, spectral data, and alternative route whenever possible.
