Reactio 3-phenylaminocyclopent-2-en-1-una cum 4-methylo, 4-methoxy et 4-chlorobenzenediazonii tetrafluoroboratis adhibita ad comparandas productorum 3a-c iuncturae azo.Compertum est has compositiones tam CDCl inesse (III) solutione et solida periodo fere exclusive sicut (E)-3-phenylamino-2-(4-subst.phenyldiazenyl)cyclopent-2-en-1-quae cum N-. -H...N consectetuer vinculum intramolecular.Substitutio phenyl reliquiarum diazonii salis vim non habet in positione aequilibrii tautomeric.Ex altera parte, composita 4a, b per reactionem 3-phenylamino-1H-inden-1-una cum 4-methylbenzene- benzenediazonii tetrafluoroboratorum formatorum existunt in CDCl(3) solutione et in solido periodo sicut mixtorum hydrazonum.In solutione occurrunt ut mixtura trium formarum, e quibus duae notae sunt E/Z isomers cum diversis generibus vinculorum hydrogenii.Compositum 5 formatum per reactionem 3-amino-5,5-dimethylcyclohex-2-en-1-unae cum 4-methoxybenzenediazonio tet rafluoroborato convertitur in hydrochloridem stabili 5.HCl in solutione stans CHCl(3);Hoc productum ostendit eminentem gradum delocalizationis criminis affirmativi.Eius structura per X-ray studuit.
