    Formation of pyridazinium salts by reaction of benzendiazonium salts and enaminones

  • Original language description

    We found out that some enaminones derived from benzoylacetone form by reaction with excess of various benzenediazonium salts under anhydrous conditions both expected hydrazone and azo coupled pyridazinium salt . Yield of pyridazinium salt is increased byusing of diazonium-hexafluorophosphate. Structure of these salts has been studied by means of multinuclear magnetic resonance and by X-ray diffractometry.

    Tvorba pyridaziniových solí reakcí benzendiazoniových solí a enaminonů

  • Czech description

    Zjistili jsme, že některé enaminony odvozené od benzoylacetonu tvoří reakcí s přebytkem benzendiazoniových solí za bezvodých podmínek jak očekávané hydrazony i azokopulované pyridaziniové soli. Výtěžek pyridaziniových solí se zvýší použitím diazonium hexafluorofosfátů. Struktura těchto solí byla studována s použitím multinukleárních technik NMR a rentgenostrukturní analýzou.
