Ibicuruzwa

Imyitwarire ya 3-fenylaminocyclopent-2-en-1-imwe hamwe na 4-methyl, 4-mikorerexy na 4-chlorobenzenediazonium tetrafluoroborates yakoreshejwe mugutegura ibicuruzwa bihuza azo 3a-c.Byagaragaye ko ibyo bikoresho biboneka mubisubizo byombi bya CDCl (3) hamwe nicyiciro gikomeye cyane nka (E) -3-fenylamino-2- (4-subst.phenyldiazenyl) cyclopent-2-en-1-imwe hamwe na N- -H ... N imigozi ya hydrogène idasanzwe.Gusimbuza ibisigazwa bya fenyl yumunyu wa diazonium nta ngaruka bigira kumwanya wa tautomeric equilibrium.Ku rundi ruhande, ibice 4a, b byakozwe nigisubizo cya 3-fenylamino-1H-inden-1-imwe hamwe na 4-methylbenzene- cyangwa benzenediazonium tetrafluoroborates ibaho mubisubizo bya CDCl (3) no mubice bikomeye nkibintu bya hydrazone.Mubisubizo bibaho nkuruvange rwuburyo butatu, muribwo bubiri bwamenyekanye nka E / Z isomers hamwe nubwoko butandukanye bwa hydrogène.Igiteranyo cya 5 cyakozwe nigisubizo cya 3-amino-5,5-dimethylcyclohex-2-en-1-imwe hamwe na 4-mikorerexybenzenediazonium tet rafluoroborate ihinduka hydrochloride ihamye 5.HCl ihagaze mugisubizo cya CHCl (3);iki gicuruzwa cyerekana urwego rwo hejuru rwa delocalisation yuburyo bwiza.Imiterere yacyo yizwe hakoreshejwe X-ray.
