Nā huahana

Ua hoʻohana ʻia ka hopena o 3-phenylaminocyclopent-2-en-1-one me 4-methyl, 4-methoxy a me 4-chlorobenzenediazonium tetrafluoroborates no ka hoʻomākaukau ʻana i nā huahana hoʻohui azo 3a-c.Ua ʻike ʻia aia kēia mau pūhui i loko o ka hoʻonā CDCl(3) a me ka pae paʻa e like me (E) -3-phenylamino-2-(4-subst.phenyldiazenyl)cyclopent-2-en-1-ones me N- -H...N ka pilina hydrogen intramolecular.ʻAʻohe hopena o ka hoʻololi ʻana o ke koena phenyl o ka paʻakai diazonium i ke kūlana o ka equilibrium tautomeric.Ma kekahi ʻaoʻao, ʻo nā pūhui 4a, b i hoʻokumu ʻia e ka hopena o 3-phenylamino-1H-inden-1-one me 4-methylbenzene- a i ʻole benzenediazonium tetrafluoroborates aia i loko o ka hoʻonā CDCl(3) a ma ka pae paʻa e like me nā pūhui hydrazone.I loko o ka hoʻonā ʻana, loaʻa lākou ma ke ʻano he hui ʻana o ʻekolu mau ʻano, mai loko mai o ia mau mea ʻelua i ʻike ʻia he isomers E/Z me nā ʻano paʻa hydrogen like ʻole.ʻO ka hui 5 i hoʻokumu ʻia e ka hopena o 3-amino-5,5-dimethylcyclohex-2-en-1-one me 4-methoxybenzenediazonium tet rafluoroborate ua hoʻololi ʻia i loko o kahi hydrochloride paʻa 5.HCl ma ke kū ʻana i ka hopena CHCl(3);hōʻike kēia huahana i kahi kiʻekiʻe o ka delocalization o ka uku kūpono.Ua aʻo ʻia kona ʻano me ka X-ray.
