Metal complexes containing diastereoisomers and enantiomers of o-phenylenebis(methylphenylarsine) and its phosphorus analogue. 3. Preparation and stereochemistry of octahedral bis(bidentate)dichlororuthenium(II) complexes

A detailed investigation of the stereochemistry of cis- and trans-[RuCl2(bidentate)2] containing the diastereoisomers and enantiomers of o-phenylenebis(methylphenylarsine) and its phosphorus analogue has been undertaken. The trans complexes were prepared in high yield from the ligands and a prereduced form of commercial ruthenium(III) chloride in the presence of aqueous formaldehyde. The optically active, racemic, meso, syn, and anti forms of the trans-dichloro complexes were isolated for both ligands, and each of these was subsequently isomerized to the corresponding cis compound by reaction with triethylaluminum. The various diastereoisomeric cis-dichloro compounds were also separated and characterized. Whereas the trans-dichloro isomers were relatively inert, the cis complexes readily underwent stereospecific halogen substitution by iodide ions and carbon monoxide.
