Abstract

The ring-chain tautomerism of alkyl-substituted 6-hydroxytetrahydro-1,3-thiazine-2-thiones was studied by IR spectroscopy and mass spectrometry. The dependence of the tautomeric equilibrium on the number and location of the methyl groups in the molecule and the aggregate state of the substance was ascertained. Substituted 3,4-dihydro-2H-1,3-thiazine-2-thiones were obtained by the dehydration of the 6-hydroxytetrahydro-1,3-thiazine-2-thiones
