Convenient access to the enantionerically pure, conformationally rigid, ligand has been established by intramolecular [4 + 2]-Diels-Alder cycloaddition between dicyclohexylvinylarsine and 3,4-dimethyl-1-phenylphosphole using chiral organopalladium(II) complexes containing orthometallated (S)-1-α-(dimethylamino)ethylnaphthalene or (R)-2-α-(dimethylamino)ethylnaphthalene as the reaction templates. The ligand was displaced from the palladium complex with cyanide and reacted with [η6-arene)RuCl2]2 and NH4PF6 to form diastereomeric [η6-arene)Ru(P-As)Cl]PF6 complexes, chiral at ruthenium. New complexes have been characterized by elemental analyses, electrochemistry, and electronic, circular dichroism, 1H-, 1H{31P}-, 13C{1H}- and 31P{1H}-NMR spectroscopies, and in several cases, by X-ray crystallography.
