Abstract

Cyclocondensation of N-prop-2-ynyl-o-phenylenediamine with phenyl isothiocyanate leads to the formation of 1-(3-arylprop-2-ynyl)-2,3-dihydro-1H-benzimidazole-2-thiones. In the reactions of diacetylene derivatives  − N-penta-2,4-diynyl-o-phenylenediamine - with phenyl isothiocyanate the formation of two heterocyclic nuclei occurs simultaneously to form [1,3]thiazolidino[3,2-a]benzimidazoles.
