Several cobalt salen complexes were synthesized. Early solubility issues were solved by adding cyclohexyl and phenyl substituents to the diamine backbone of the ligand. Crystals were obtained for complexes 18, 20, and 21. These complexes represent a series of compounds differing only in number of electron withdrawing substituents. Cyclic voltammetry was performed on 18, 20, and 21 to probe the catalytic activity of each compound. Initial CVs were taken in acetonitrile solutions. Subsequent CVs were taken with additions of TFA to prove the catalytic activity of each complex. It was found that 21, containing the most electron withdrawing substituents, was the most active and had the most positive redox couple followed by 20. 18 exhibited a very negative redox couple at -1.37 V and showed no catalytic activity.
