It was demonstrated by PMR spectroscopy that alkylidene derivatives of vic-(N-alkylhydrazino)thiols in solutions exist exclusively in the cyclic form, i.e., as perhydro-1,3,4-thiadiazines.Only pinacolone derivatives undergo reversible isomerization to the corresponding hydrazones.The thermodynamic parameters of the ring chain equilibria were determined.The static stereochemistry and the dynamics of the conformational transitions of perhydro-1,3,4-thiadiazines are discussed.
