hidroxylation of phenol with H2O2 catalyzed by CoII complexes encapsulated in zeolite -Y

the hydroxylation of phenol using cobalt II complexes of bidentate ligand N,N-ethylenebis salicylideneamine salen N,N- propylenbis salicylideneamine salpn and N,N- phenylenebis salicylideneamine salophen were investigatted. These complexes catalyze the liquid -phase hydroxylation of phenol with H2O2 to catechol as a major product and hydroquinone as a minor product .
