This way and that : Ruthenium complexes with asymmetric bidentate phosphine ligands bearing two substituents that differ in size (green spheres) produce a totally alternating copolymer of norbornene and cyclooctene by ring‐opening metathesis polymerization (ROMP). The E/Z ratio can be influenced systematically by changing the bulkiness of the aryl sulfonate ligand (blue rectangles).
