Ko te tauhohenga o te 3-phenylaminocyclopent-2-en-1-one me te 4-methyl, 4-methoxy me te 4-chlorobenzenediazonium tetrafluoroborates i whakamahia hei whakarite i nga hua honohono azo 3a-c.I kitea ko enei pūhui kei roto i te otinga CDCl(3) me te wahanga totoka ko (E)-3-phenylamino-2-(4-subst.phenyldiazenyl)cyclopent-2-en-1-one me N-. -H...N herenga hauwai i roto i te ngota.Ko te whakakapi i te toenga phenyl o te tote diazonium kaore he painga ki te waahi o te taurite tautomeric.I tetahi atu taha, ko nga pūhui 4a, b i hangaia e te tauhohenga o te 3-phenylamino-1H-inden-1-one me te 4-methylbenzene- ranei benzenediazonium tetrafluoroborates kei roto i te otinga CDCl(3) me te wahanga totoka hei pūhui hydrazone.I roto i te otinga ka puta hei ranunga o nga ahua e toru, i roto i enei e rua i tautuhia ko nga imaera E/Z me nga momo here hauwai rereke.Ko te kohinga 5 i hangaia e te tauhohenga o te 3-amino-5,5-dimethylcyclohex-2-en-1-one me te 4-methoxybenzenediazonium tet rafluoroborate ka huri ki te hydrochloride pūmau 5.HCl i te tu i te otinga CHCl(3);Ko tenei hua e whakaatu ana i te nui o te whakakorenga o te utu pai.Ko tona hanganga i akohia e te X-ray.
