ABSTRACT

The role played by hydrogen bonds and supramolecular macrostructures, in the mechanisms of homogeneous and enzymatic catalysis (nickel and iron complexes) is discussed. The AFM method has been used for research of possibility of the stable supramolecular nanostructures formation based on effective catalysts of ethylbenzene oxidations and Dioxygenases models: iron complexes FeIIIx(acac)y18C6m(H2O)n and nickel complexes NixL

5.1 INTRODUCTION

However, the findings on the mechanism of action of enzymes, and, in particular, dioxygenases and their models, are very useful in the treatment of the mechanism of catalysis by metal complexes in the processes of oxidation of hydrocarbons with molecular oxygen. Moreover, as one will see below, the investigation of the mechanism of catalysis by metal complexes can give the necessary material for the study of the mechanism of action of enzymes.
