| Abstrakt: |
The reaction of phenylcyanoacetylene with imidazolethiones was studied. It is shown that in the presence of 5–10% KOH the addition of phenylcyanoacetylene is accompanied by intramolecular cyclization with the formation of imidazo-1,3-thiazines. An increase in the amount of catalyst to 20% leads to cleavage of the thiazine ring at the C-S bond and the formation of the corresponding acrylonitrile derivatives. Products of addition of 2 moles of phenylcyanoacetylene were obtained. |
