Synthesis of Hexasap Macrocyclic Ligand with Six Tridentate Sap Chelating Units and Its Gallium Complex
Mamoru Kamisaka, Sara Machleit, Takashi NakamuraAbstract
We report the synthesis of the macrocyclic ligand hexasap (H121), which incorporates six ONO-type tridentate ligand sap (salicylidene-aminophenol) units. The ligand was prepared from the bifunctional monomer 2 bearing an o-aminophenol group and an acetal-protected salicylaldehyde group. A hexanuclear Ga complex of hexasap exhibits a well-defined architecture characterized by a regular arrangement of the coordinating ligands within its cavity.
