โœฆ Synopsis

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 Ga 3+ among trivalent cations of Group 13 elements.

A novel tripodal hexadentate ligand, consisting of three catechol units, three isobutenyl ether arms, and one aromatic core, was synthesized through four steps, in which the Claisen rearrangement was included as the key step. The hexadentate ligand formed a 1:1 complex with iron(III) trichloride hex
