Reaction of hydrazinecarbothioamides with 2-bromoacetophenones furnished the formation of thiazole-, bisthiazole-, pyrazoleand 1,3,4-thiadiazolederivatives in good yields. The mechanism was discussed. The structures of products were proved by MS, IR, NMR, elemental analyses and X-ray structure analyses.
