Abstract
Products of condensation of vicinal hydrazino thiols with aromatic carbonyl compounds, which were found to be mixtures of one acyclic tautomer (a hydrazone) and two stereoisomers with a cyclic form (perhydro-1,3,4-thiadiazine), were obtained. The tautomeric and stereoisomeric equilibria constants were determined by PMR spectroscopy.
