Abstract
The synthesis of tetradentate cobalt(II) salicylaldiminato complexes and their catalytic evaluation in the oxidation of phenol is reported. Tetradentate cobalt complexes [Co(L n ) 2] were obtained by reacting the N-(aryl)salicylaldimine ligands ( HL 1– HL 6) with cobalt acetate in a 2:1 mole ratio. All complexes were characterized using FT-IR and elemental analysis. X-ray crystal structures of complexes 1, 2 and 5 have also been obtained. All complexes were found to be active for the oxidation process.
