The original method of modification of homogeneous catalysts, nickel complexes, with additions of extra ligands-modifiers, L2, proposed by L.I. Matienko, to increase the effectivity of the catalysts in selective oxidation of alkylarens to hydro peroxides is discussed. Modeling of catalytically active nickel complexes as catalysts for selective oxidation of ethy lbenzene in α-phenyl ethyl hydro peroxide with the binary system {NiII(acac)2+L2} by introduction of the third component of phenol (PhOH), successfully implemented by L.I. Matienko and L.A. Mosolova. The mechanism of action of the triple hetero bimetallic complexes NiII(acac)2∙MSt∙PhOH (MSt=NaSt, LiSt), formed in the selective oxidation of ethyl benzene, is researched. The role of micro steps of chain initiation (O2 activation) and propagation at the assistance of the catalyst (Ct + RO2• →) in the selective ethyl benzene oxidation is assessed.
