    Description / Table of Contents: Thermolysis of ν-Triazolyl DerivativesReaction of heterocycles bearing a chlorine adjacent to a ring nitrogen atom with ν-tiazole at 60-160° results in the formation of 1-ν-triazolyl-derivatives (3) or in subsequent elimination of nitrogen and formation of condensed imidazo heterocycles. Of the l-ν-triazolyl-derivatives only the pyrimidine derivative 3c can be transformed into the corresponding imidazo pyrimidine 4. The others undergo another kind of decomposition, which leads to undefined products.
    Notes: Heterocyclen mit Chlor in Nachbarstellung zum Ringstickstoff reagieren bei 60-160° mit ν-Triazol zu den entsprechenden ν-Triazolyl-(1)-Derivaten (3) oder weiter unter Stickstoffabspaltung zum kondensierten Imidazo-Heterocyclus. Von den ν-Triazolyl-(1)-Derivaten konnte nur das Pyrimidin-Derivat 3c durch Thermolyse in Polyphosphorsäure in das entsprechende Imidazo-pyrimidin 4 übergeführt werden. Die übrigen erleiden andersartige, zu undefinierten Produkten führende Zersetzung.
