The reaction of benzoyl isothiocyanate with hydrazine derivatives. Part II. Reaction with some alkyl hydrazones
Abstract
The reaction of benzoyl isothiocyanate with 1-alkyl-2-isopropylidenehydrazines leads to the formation of 1,3,4,6-oxatriazepine-5-thione derivatives rather than the open-chain benzoyl thiosemicarbazones
PhCO·NH·CS·NR·N:CMe2. The related benzylidenehydrazines gave non-cyclic products under comparable conditions. Structural assignments have been made largely on the basis of spectral data. Acid hydrolysis of the oxatriazepinethiones to 1,2,4-triazoline-5-thiones has also been studied.
