A new simple method has been used to prepare 6-substituted 4-(subst. amino)-5-aryldiazenyl-l-arylpyridazinium salts from N-methyl- or N-aryl-3-amino-l-phenylbut-2-en-l-ones and 4-aminopent-3-en-2-ones and substituted benzenediazonium tetrafluoroborates or hexafluorophosphates. The structure of selected derivatives was studied by means of N-15 NMR spectra and X-ray.

Abstract
A new simple method has been used to prepare 6-substituted 4-(subst. amino)-5-aryldiazenyl-l-arylpyridazinium salts from N-methyl- or N-aryl-3-amino-l-phenylbut-2-en-l-ones and 4-aminopent-3-en-2-ones and substituted benzenediazonium tetrafluoroborates or hexafluorophosphates. The structure of selected derivatives was studied by means of N-15 NMR spectra and X-ray.File in questo prodotto:
