ABSTRACT

In this chapter, we research the kinetics and mechanism of selective ethylbenzene oxidation with dioxygen catalyzed by triple catalytic systems {NiII(acac)2 + L

2 + PhOH, PhOH = phenol} (L2 = HMPA, MP (MP = N-methylpyrrolidone-2)). With atomic force microscopy (AFM) method, the possibility of forming the stable supramolecular nanostructures based on triple systems, {NiII(acac)2 + HMPA(MP)+ PhOH}, due to intermolecular H-bonds was researched. We also used AFM method to study the possibility of formation of stable supramolecular nanostructures based on triple system {NiII(acac)2 + L

2 + Tyr} (Tyr = L-Tyrosine, L2 = MP or L-Histidine), that is, structural and functional model of Ni-Acireductone Dioxygenase (Ni-ARD),—with the assistance of intermolecular H-bonds. The bibliography includes 22 references.
