Reactions of Copper(II) with Ligands Containing Thioether Donors

Preparations of three ligands containing thioether donor atoms are detailed and their interactions with cupric ions discussed.The affinity of these sulfur donors for copper(II) is small, and stable complexes can only be formed under restricted solvent and anion conditions.
