The aim of the book “Oxygen atom transfer reactions” is to outline some recent developments in the studies of oxygen atom transfer mechanisms in catalytic oxidation reactions based on several fundamental mechanistic insights in this area. In this context, the book also permits the reader to acquaint with the classification of the general types of oxidation reactions from the point of view of the reaction mechanism and the possibility of oxygen atom transfer mechanisms in them.
The foreword of the volume was written by Jinkai Zhao, academician of the Chinese Academy of Sciences and member of the European Academy of Sciences.
This volume consists of four chapters covering various aspects of oxygen atom transfer reactions widespread in nature and man-made chemical systems.
The introductory chapter written by the editor of the book “Oxygen atom transfer reactions” provide general insight into the oxygen atom transfer mechanisms in different chemical systems. Presently, at least two main branches of the oxidative catalysis or photocatalysis are closely related to the mechanistic studies of oxygen atom transfer reactions. One of them is catalytic oxidation of water and the other catalytic, enzymatic or aerobic oxidation of various substrates. Both they mainly occur through the oxygen atom transfer reactions catalyzed by the transition metal-organic complexes. The oxidation reaction mechanisms have been presented underlying the role of nature of the central metal or metal-ion and the coordinated ligands, including their electronic structures, in these complexes.
The review article by Liao and Lyn is devoted to some efficient catalytic strategies (bio-inspiration, biomimetics, design of synthetic models of enzymes and industrial catalysts) for the activation of dioxygen and functionalization of C-H and C=C bonds driven by oxygen atom transfer reactions from the metal-oxo complexes to substrates. This review describes in detail how some enzymes, such as cytochrome P450, methane monooxygenase, dioxygenases activate dioxygen and selectively transfer oxygen atoms to substrates. The authors also present a new efficient strategy for redox catalyst design related to the Lewis acid promoted dioxygen activation by some transition metal complexes, which in this case demonstrate a high efficiency in catalytic hydrogen atom abstraction reaction.
A separate chapter of this collection is written by Sankaralingam M. and Rajeev R., devoted to the oxygen atom transfer reactions catalyzed by nickel complexes. According to the authors of this chapter, unlike investigations of organometallic complexes of Fe and Mn, “many researchers have been interested to uncover the involvement of nickel in biologically important molecules only after the discovery of the first-ever nickel-containing metalloenzyme urease”. Many interesting effects related to the stereoelectronic properties of ligand architecture in Ni-organometallic complexes in reactions of catalytic oxygen atom transfer or hydrogen atom abstraction reactions have been outlined here.
The last chapter of the book Oxygen atom transfer reactions is a review article entitled “Mechanisms of some heterogeneous photocatalytic reactions of oxidation occurring via oxygen atom transfer” also written by the editor. The author provides the reader with various types of photochemical oxidation reactions of organic compounds which occur through the mechanisms of oxygen atom transfer in heterogeneous catalytic systems, under visible light or UV irradiation. It has been shown by a number of examples that by heterogenization of photocatalyst exhibiting catalytic activity in homogeneous conditions, it is possible to improve the ability of metal-organic complexes to transfer oxygen atoms in oxidation-reduction reactions.
The overall content of the book shows how the revelation of the detailed mechanism of oxygen atom transfer reactions opens up new possibilities for creating well-controllable oxidation processes.
The book Oxygen atom transfer reactions is addressed to professional scientists in the fields of chemistry, biology and some applied sciences (chemical engineering, biotechnology, pharmacology), as well as graduate and undergraduate students interested in understanding the mechanisms of oxidation reactions.
About the editor:
Dr. Robert Bakhtchadjian is a physical chemist, a graduate of the Chemistry Department of Yerevan State University. He received his Ph. D. degree in chemistry at the Institute of Chemical Physics of the Academy of Sciences of Armenia. He held a post-doctoral position in the laboratory of CNRS at the University of Aix-Marseille (France). As a research chemist he held various positions at the Institute of Chemical Physics, as well as at the University of Aix-Marseille (France), before heading the scientific group of Franco-Arminian Cooperation jointly supported by CNRS of France and SCS of Armenia.
His scientific interests include various aspects of the reaction mechanisms of oxidation processes related to the interactions of active intermediate species (atoms, radicals, excited species) on the surfaces of solid substances and in the fluid phases. He has particular interests in the chemistry of transition metal-organic compounds, their synthesis, characterisation and the study of their catalytic, including photocatalytic activity, in homogeneous and heterogeneous oxidation reactions.
He is the author or co-author of 90 scientific publications: monographs, edited books, chapters of the books and review articles, certificates of authorship, articles in the scientific journals, entries in the international databases. His main monograph Bimodal oxidation: Coupling of Heterogeneous and Homogeneous Reactions was published in 2019. He is also founder and editor of the book series “Chemical Reaction Mechanisms” at Bentham Science (the first volume was a collection Oxygen Atom Transfer Reactions).
Dr. Bakhtchadjian is a member of several scientific organizations and the founding president of the Association “ABC” (France, 2003). He was a grantee from: CNRS (multiple, France); Aix-Marseilles University; SCS of Armenia; International Science Foundation (USA). He was awarded the Prize of the Economic Commission of Marseille-Provence-Metropole (France, 1999). His biography has been included in “Marquis Who’s Who in the World” (since 15th edition), and over 20 other international biographical publications.
