摘要：
Facile stereoselective synthesis of an enantiomerically pure DELTA-Ru-trisbipyridine type complex is accomplished by using a new chiral and conformationally rigid ligand, which completely predetermines the helical chirality of the metal, yielding exclusively DELTA-configuration in the present case. The ligand, abbreviated chiragen[6] is a bisbipyridine compound, where two pinene substituted bipyridine units are linked through an aliphatic C6-chain. The two remaining coordination sites of the complex are occupied by 4,4'-dimethylbipyridine. The structure of the DELTA-[Ru(chiragen-[6])(4,4'-dimethylbipyridine)](CF3SO3)2 complex has been determined by X-ray crystallography. Metal complexes formed by chiragen ligands have potential applications in enantioselective catalysis and as chiral building blocks for polynuclear species.
