Reactions with Hydrazonoyl Halides. Part XXV. 1 Synthesis of Some New 2,3-Dihydro-1,3,4-thiadiazoles and 5-Arylazothiazoles

Abstract

2,3-Dihydro-1,3,4-thiadiazoles are synthesized by the reaction of hydrazonoyl halides with alkyl benzoylhydrazinecarbodithioates in ethanolic triethylamine whereas α-keto hydrazonoyl halides react with benzoylthiosemicarbazides to afford 5-arylazothiazoles.
