摘要：

C-acyl-N-phenyllhydrazonoyl halides 1a-g have 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,b react with alkyl carbodithioates (14 or 15)a-m afforded 2,3-dihydro-1,3,4-thiadiazoles in good yields. Structures of the new compounds were eludicated on the basis of elemental analyses, spectral data, and alternative methods of synthesis whenever possible.
