Özet

4'-Formylbenzo(15-crown-5)-2-carboxyphenylhydrazone (CPH) was synthesized by the addition reaction of 2-carboxyphenylhydrazine and 4'-formylbenzo(15-crown-5). 1,5 Bis(2'-carboxyphenyl)-3-benzo(15-crown-5) formazan (CPF) and 1-(2'-carboxyphenyl)-5-(2'-hydroxy-4'-carboxyphenyl)-3-benzo(15-crown-5)formazan (HPF) were then synthesized by coupling the diazonium salts of 2-aminobenzoic acid and 3-amino-4-hydroxybenzoic acid with 4'-formylbenzo(15-crown-5)-2-carboxyphenyl-hydrazone in strong alkaline media. The copper(II) and cobalt(III) complexes of these formazans have also been isolated. The structure of the formazans and their Cu(II) and Co(III) complexes were evaluated by elemental analysis, H-1-NMR, IR and UV-VIS spectra.
