Abstract
The synthesis of a number of substituted 4-hydroxyhexahydropyrimidine-2-thiones has been effected. The prototropic ring-chain tautomerism of compounds of this type in chloroform solution has been investigated by IR spectroscopy. The dependence of the relative stability of the cyclic tautomeric forms on the structures of the compounds studied has been elucidated.
