The method proposed by the authors of a modification of the homogeneous catalysts, nickel complexes, with use of the addition of exo ligands – modifiersis for selective catalytic oxidation with molecular oxygen alkylarene to hydroperoxides is discussed. The phenomenon of unusually high catalytic activity of triple complexes NiII(acac)2∙L2∙PhOH, including as activating ligands electron donating ligand L2 and phenol, formed in the selective ethylbenzene oxidation to a - phenyl ethyl hydroperoxide, catalyzed with triple system {NiII(acac)2+L2+PhOH}, is examined. The mechanism of action of the triple complexes in the selective oxidation of ethylbenzene is researched. The possibility of formation of stable supramolecular structures based on ternary complexes NiII(acac)2∙NaSt∙PhOH with metalloligandom NaSt as L2 has been investigated with use of the AFM (atomic force microscopy) method.
