Abstract:
The mononuclear [Ru(bpy)(2)(bpym)][PF(6)](2) complex (bpy = 2,2'-bipyridine; bpym = 2,2'-bipyrimidine) has been prepared in its enantiopure Lambda form. Because of the chelating property of the bipyrimidine moiety, it is possible to use this chiral-at-metal complex as a chiral inorganic ligand for a second metal cation acting as a catalytic center. Here we report the synthesis and the structural characterization of a novel dinuclear Lambda-[(bpy)(2)Ru(bpym)RuCl(p-cymene)](3+) compound (1). The asymmetric-inducing properties of the enantiopure chiral-at-metal metalloligand have been probed during asymmetric transfer hydrogenation to ketones catalyzed by 1. This provides one of the very few illustrations of the potential of this original class of chiral inorganic ligands.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
