The reaction of benzimidazole-2-thione with phenylcyanoacetylene and a tertiary cyanoacetylene alcohol in the presence of alkali in DMSO was studied by PMR.At the first stage the thione adds at the CC bond of the cyanoacetylenes with the formation of t

The reaction of phenylcyanoacetylene with imidazolethiones was studied.It is shown that in the presence of 5-10percent KOH the addition of phenylcyanoacetylene is accompanied by intramolecular cyclization with the formation of imidazo-1,3-thiazines.An inc
