Solution and solid state structure and tautomerism of azo coupled enaminone derivatives of benzoylacetone

Original language description

The reaction of 4-substituted benzenediazonium tetrafluoroborates with 3-amino-1-phenylbut-2-en-1-one, 4-amino-4-phenylbut-3-en-2-one and their N-aryl derivatives 1a-1g has been used to prepare the respective azo coupling products i.e. compounds 2-5 fromenaminone 1a, compounds 6-9 from enaminone 1c, compound 10 from enaminone 1d, compound 11 from enaminone 1e, compounds 12, 13 from enaminone 1f, compounds 14, 15 from enaminone 1b and compound 16 from enaminone 1g. Tautomerism of the azo coupling products prepared has been investigated in CDCl3 solutions by means of 1H, 13C and 15N NMR spectra. Crystal structures of selected products have also been investigated by means of X-ray diffraction.

Czech description

Reakcí 4-substituovaných benzendiazonium-tetrafluoroborátů s 3-amino-1-fenylbut-2-en-1-onem, 4-amino-4-fenylbut-3-en-2-onem a jejich N-arylderiváty 1a-1g byly připraveny produkty azokopulace: z enaminonu 1a látky 2-5, z enaminonu 1c látky 6-9, z enaminonu 1d látka 10, z enaminonu 1e látka 11, z enaminonu 1f látky 12, 13, z enaminonu 1b látky 14, 15 a z enaminonu 1g látka 16. Pomocí 1H, 13C a 15N NMR spekter byla studována tautomerie produktů azokopulace v roztoku v CDCl3. U vybraných látek byla studována struktura v krystalu pomocí X-ray.
