Synthesis and Metal Complexation of Twovic-Dioxime Derivatives of Calix[4]Arenes
摘要:
Two new vic-dioxime compounds of calix[4]arene and their transition metal complexes were synthesized from 28-[(4-aminobenzyl)oxy]-25,26,27-tribenzoyl-oxycalix[4]arene and amphi-chloroglyoxime or amphi-dichloroglyoxime. The complexes of these compounds with Ni(II), Cu(II) and Co(II) ions were investigated. All of the complexes of these ligands are tetrahedral with a metal-ligand ratio of 1:2. The prepared compounds were characterised based on H-1 NMR and IR spectra as well as elemental analyses.
