Abstract

Abstract : By varying the metal/ligand ratio, either dinuclear triple helicate or mononuclear pincer can be stereo-selectively obtained from the same chiral ligand. Their catalytic properties have been demonstrated with the asymmetric FC alkylation reactions. Abstract : By varying the metal/ligand ratio, either dinuclear triple helicates ( ΛΛ / ΔΔ -La2 L R / S 3 ) or mononuclear pincer complexes ( Λ / Δ -LaL R / S ) can be stereo-selectively obtained from the same chiral bis-tridentate ligand (L R / S ). Due to the open metal sites available in both complexes, their catalytic properties have been demonstrated with the asymmetric Friedel–Crafts alkylation reactions.
