Synthesis and Characterization of Hetero- and Homobimetallic Complexes of New Hard-Soft Binucleating Ligands

A unique feature of our unsymmetrical ligand systems is the arrangement of hard and soft donor atoms in a manner to preclude its functioning as a tridentate chelating agent. We have prepared a series of functionalized (beta)-diketone ligand systems via the Claisen condensation of orthosubstituted methyl benzoate compounds with the potassium enolate of methyl ketones. The new binucleating ligands prepared in this work include phosphine, thioether and quinoline substituted (beta)-diketones along with the Schiff-base derivatives of the thioether (beta)-diketone. With these ligand systems, we can exploit the extensive transition metal coordination chemistry of (beta)-diketonates and of "soft" donor groups to prepare complexes containing two different metals. The coordination chemistry of o-diphenylphosphinobenzoylpinacolone, HacacP, has been most extensively studied.
