Abstract

Multimetallic salen and related Schiff base complexes designed for cooperative asymmetric catalysis are introduced. First, studies to enhance the cooperative function of two distinct metal–salen units using covalently linked metal–salen complexes, supramolecular bimetallic salens as well as μ-oxo-bridged metal salens are described. Then, studies to design dinuclear Schiff base catalysts that exhibit unique intramolecular cooperative functions of two distinct metals are discussed in detail.
