Iimveliso

Ukusabela kwe-3-phenylaminocyclopent-2-en-1-enye kunye ne-4-methyl, i-4-methoxy kunye ne-4-chlorobenzenediazonium tetrafluoroborates yayisetyenziselwa ukulungiselela iimveliso zokudibanisa i-azo 3a-c.Kwafunyaniswa ukuba ezi khompawundi zikhona kuzo zombini ii-CDCl (3) isisombululo kunye nesigaba esiqinileyo ngokukodwa (E) -3-phenylamino-2- (4-subst.phenyldiazenyl) cyclopent-2-en-1-ones nge-N- -H...N intramolecular hydrogen bond.Ukutshintshwa kwentsalela ye-phenyl yetyuwa ye-diazonium ayinayo impembelelo kwindawo yokulingana kwe-tautomeric.Ngakolunye uhlangothi, i-compounds 4a, b eyenziwe yi-reaction ye-3-phenylamino-1H-inden-1-enye kunye ne-4-methylbenzene- okanye i-benzenediazonium tetrafluoroborates ikhona kwi-CDCl (3) isisombululo kunye nesigaba esiqinileyo njenge-hydrazone compounds.Kwisisombululo zivela njengomxube weefom ezintathu, apho ezimbini zichongwe njenge-isomers ze-E / Z ezineentlobo ezahlukeneyo zeebhondi ze-hydrogen.I-Compound 5 eyenziwe yi-reaction ye-3-amino-5,5-dimethylcyclohex-2-en-1-enye ene-4-methoxybenzenediazonium tet rafluoroborate iguqulwa ibe yi-hydrochloride ezinzileyo 5.HCl ekumeni kwi-CHCl (3) isisombululo;le mveliso ibonisa iqondo eliphezulu le-delocalization yentlawulo efanelekileyo.Indlela eyakhiwe ngayo yahlolisiswa kusetyenziswa iX-reyi.
