benzofuran moiety were prepared from the reaction of 2‐(2‐phenylhydrazono)‐1‐(5‐bromobenzofuran‐2‐yl)‐2‐chloroethanone with each of potassium thiocyanate, potassium selenocyanate, alkyl carbodithioate, and pyrmidine‐2‐thione derivatives. All the newly synthesized compounds were confirmed by elemental analysis, spectral data, and alternative route synthesis whenever possible.

C-acyl-N-phenyllhydrazonoyl halides 1a–ghave been caused to react with 3-(aminomethylthiomethyl)-2H-chromen-2-one in the presence of triethylamine to give triazoles. Also, C-acyl-N-pyrazolylhydrazonoyl chlorides 13a, breact with alkyl carbodithioates (14or 15) a–mafforded 2,3-dihydro-1,3,4-thiadiazoles in good yields. Structures of the new compounds were elucidated on the basis of elemental analyses
