Ruthenium(II) complexes with the unsymmetrical diphosphinomethanide [PPh2CHPtBu2]- containing isocyanides and chiral amines as ancillary ligands were prepared, and the molecular structure of [Ru(CNtBu)4{PPh2CHPtBu2}]+ was studied by X-ray crystallography. The reactivity of the coordinated methanide toward [AuCl(PPh3)] was investigated, leading to the stereoselective formation of the chiral metallodiphosphine [PPh2CH(AuPPh3)PtBu2].
