O le tali a le 3-phenylaminocyclopent-2-en-1-one ma le 4-methyl, 4-methoxy ma le 4-chlorobenzenediazonium tetrafluoroborates na faʻaaogaina e saunia ai mea faʻapipiʻi azo 3a-c.Na maua o nei mea faʻapipiʻi o loʻo i ai i le CDCl(3) fofo ma le vaega malosi e masani lava o le (E) -3-phenylamino-2-(4-subst.phenyldiazenyl)cyclopent-2-en-1-ones ma N- -H...N i totonu o le hydrogen bond.O le suia o le phenyl o totoe o le masima diazonium e leai se aoga i le tulaga o le tautomeric equilibrium.I le isi itu, o le tuufaatasiga 4a, b faia e ala i le tali atu o le 3-phenylamino-1H-inden-1-tasi ma le 4-methylbenzene- poʻo le benzenediazonium tetrafluoroborates o loʻo i ai i le CDCl (3) solution ma i le vaega mautu e pei o le hydrazone compounds.I le fofo latou te tupu o se faʻafefiloi o ituaiga e tolu, lea e lua na faʻamaonia o E / Z isomers ma ituaiga eseese o faʻamauga hydrogen.Fa'aputuga 5 fa'atupuina i le tali atu o le 3-amino-5,5-dimethylcyclohex-2-en-1-one fa'atasi ma le 4-methoxybenzenediazonium tet rafluoroborate ua liua i se fa'amauga hydrochloride 5.HCl i luga o le tu i le CHCl(3) solution;o lenei oloa o loʻo faʻaalia ai se maualuga maualuga o le faʻaogaina o le tau lelei.O lona fausaga na suʻesuʻeina e ala i le X-ray.
