Synthesis and binding properties of new tripodal hexadentate ligands having three quinolinol moieties for trivalent metal cations
摘要:
Tripodal hexadentate ligands, having three 8-hydroxyquinolyl or 2-methyl-8-hydroxyquinolyl groups as binding sites, were successfully prepared from the corresponding tris(isobutenyl 8-quinolyl ether) via the Claisen rearrangement. The 2-methyl-8-hydroxyquinolyl derivative exhibited binding ability for several kinds of trivalent metal cations to form 1:1 complexes, and showed selective extractability for Ga3+ among trivalent cations of Group 13 elements.
