Abstract
Schiff-Base complexes of bis-5-phenylazosalicylaldehyde ethylenediimine and bis-5-phenylazosalicylaldehyde-O-phenylenediimine ligands with Co(II) (I and II) have been synthesized and characterized by their IR spectra and elemental analyses. These complexes catalyze the oxidation of styrene in the presence of dioxygen and excess pyridine. The effect of the reaction conditions on the oxidation of styrene was studied by varying solvent, nature and amount of the catalyst and substrate. The catalytic behavior of the studied complexes was shown to be dependent on the conditions applied. In all reactions, acetophenone and 1- phenylethanol were the only observed products.
Highlights
The ability of certain cobalt (II) complexes to reversibly bind dioxygen was discovered many decades ago [1,2]
We report the oxidation of styrene by molecular oxygen in the presence of excess aromatic base to the corresponding 2–ketone and 2–alcohol using the complexes I and II as catalysts
Cobalt complexes were characterized by elemental analysis and IR spectroscopy
Summary
The ability of certain cobalt (II) complexes to reversibly bind dioxygen was discovered many decades ago [1,2]. We report the oxidation of styrene by molecular oxygen in the presence of excess aromatic base to the corresponding 2–ketone and 2–alcohol using the complexes I and II as catalysts.
