Preparation and study of the structure of pyridazinium salts formed by azocoupling reaction of enaminones
Original language description
N-Methylaminopent-3-en-2-one reacts with benzenediazonium salts to give exclusively the product if the molar ratio of enaminone and diazonium salt was 1:1. The only carbon between the carbonyl group and the amino group is attacked. In the case the molarratio of the reacting component was 1:2 (enaminone:diazonium salt) we found out that the azo coupling reaction gives also the unexpected product. This work refers to study of the structure of such salts in solution (multinuclear magnetic resonance) and in solid state (X-ray analysis) and to optimization of their synthesis.

Příprava a studium struktury pyridaziniových solí vzniklých azokopulací enaminonů
Czech description
N-Methylaminopent-3-en-2-on reaguje s benzenediazoniovými solemi za vzniku produktu v němž je molární poměr enaminonu a diazoniové soli 1:1. Atakován je uhlík mezi karbonylovou skupinou a aminoskupinou. V případě molárního poměru výchozích látek 1:2 (enaminon:diazoniová sůl) jsme zjistili azokopulaci poskytující nečekaný produkt produkt.
