    • note
    • We thank a referee for pointing out the likely possibility of a transition state with 6-membered S/O-zinc-coordination to ligand 2. This explanation is based on the importance of a free sulfide site and its strength for primary binding. Would thioether-binding be sufficiently stable as sole first coordination point, ligands 5 and 6 should give stereoinduction with opposing signs of rotation. This was not observed.
