The preparation and characterization of Rh I , Pd II , and Pt II complexes with chiral C 2 ‐symmetrical dithioether ligands derived from 1,1′‐binaphthalene‐2,2′‐dithiol (BINAS) are reported. All complexes are fluxional in solution at room temp. Interconversion between the stereoisomers can take place through conformational equilibration of the chelate ring, and/or inversion of configuration at the stereogenic sulfur. In the solid state the palladium derivative of Me 2 BINAS shows a twisted chair conformation of the chelate ring, with both methyl groups in equatorial positions.
