Abstract

A synthetic route into cis- and trans- isomers of [OsCl₂(chiral-at- phosphorus bidentate phosphine)₂] is presented. The choice of the cis- or trans- isomer of the precursor complex [OsCl₂(DMSO)₄] (DMSO=dimethylsulfoxide) permits selective preparation of either cis-or trans- isomers of the diphosphine complex. A structural study confirms the retention of both, stereochemistry at the metal and configuration at phosphorus in proceeding from the dimethylsulfoxide complex to form trans- [OsCl₂{(R,R)-1,2-phenylenebis(methylphenylphosphine)}₂].
