Kuita kwe3-phenylaminocyclopent-2-en-1-imwe ine 4-methyl, 4-methoxy uye 4-chlorobenzenediazonium tetrafluoroborates yakashandiswa kugadzira azo coupling zvigadzirwa 3a-c.Zvakaonekwa kuti mishonga iyi iripo muzvose zviri zviviri CDCl(3) mhinduro uye nhanho yakasimba inongoita se (E) -3-phenylamino-2-(4-subst.phenyldiazenyl)cyclopent-2-en-1-ones ine N- -H...N intramolecular hydrogen bond.Kutsiviwa kwephenyl yakasara yediazonium munyu haina mhedzisiro pane chinzvimbo chetautomeric equilibrium.Kune rumwe rutivi, mishonga 4a, b inoumbwa nekuita kwe 3-phenylamino-1H-inden-1-one ine 4-methylbenzene- kana benzenediazonium tetrafluoroborates iripo muCDCl (3) solution uye muchikamu chakasimba se hydrazone compounds.Mumhinduro inoitika semusanganiswa wemafomu matatu, kubva mairi maviri akaonekwa seE / Z isomers ane marudzi akasiyana ehydrogen bond.Compound 5 yakagadzirwa nekuita kwe3-amino-5,5-dimethylcyclohex-2-en-1-one ine 4-methoxybenzenediazonium tet rafluoroborate inoshandurwa kuita hydrochloride yakagadzikana 5.HCl pakumira muCHCl (3) mhinduro;chigadzirwa ichi chinoratidza yakakwirira dhigirii delocalization yechaji yakanaka.Chimiro chayo chakaongororwa pachishandiswa X-ray.
