Imikhiqizo

Ukusabela kwe-3-phenylaminocyclopent-2-en-1-one ene-4-methyl, 4-methoxy kanye ne-4-chlorobenzenediazonium tetrafluoroborates yasetshenziswa ukulungisa imikhiqizo yokuhlanganisa ye-azo 3a-c.Kutholwe ukuthi lezi zinhlanganisela zikhona kukho kokubili isixazululo se-CDCl(3) nesigaba esiqinile ngokukhethekile (E)-3-phenylamino-2-(4-subst.phenyldiazenyl)cyclopent-2-en-1-ones nge-N- -H...N ibhondi ye-hydrogen ye-intramolecular.Ukufakwa esikhundleni kwensalela ye-phenyl kasawoti we-diazonium akunawo umthelela endaweni yokulingana kwe-tautomeric.Ngakolunye uhlangothi, izingxube ezingu-4a, b ezakhiwe ukusabela kwe-3-phenylamino-1H-inden-1-one ene-4-methylbenzene- noma i-benzenediazonium tetrafluoroborates zikhona kusixazululo se-CDCl(3) futhi esigabeni esiqinile njengezinhlanganisela ze-hydrazone.Esixazululweni zivela njengengxube yezinhlobo ezintathu, kuzo ezimbili zihlonzwe njengama-isomer e-E/Z anezinhlobo ezahlukene zamabhondi e-hydrogen.Inhlanganisela engu-5 eyakhiwe ukusabela kwe-3-amino-5,5-dimethylcyclohex-2-en-1-one ene-4-methoxybenzenediazonium tet rafluoroborate iguqulwa ibe i-hydrochloride ezinzile 5.HCl ekumeni kwe-CHCl(3) isixazululo;lo mkhiqizo ubonisa izinga eliphezulu lokususa indawo yokukhokhiswa okuhle.Ukwakheka kwayo kwahlolwa kusetshenziswa i-X ray.
