Stable radicals - molecules with odd electrons which are sufficiently long lived to be studied or isolated using conventional techniques - have enjoyed a long history and are of current interest for a broad array of fundamental and applied reasons, for example to study and drive novel chemical reactions, in the development of rechargeable batteries or the study of free radical reactions in the body. In Stable Radicals: Fundamentals and Applied Aspects of Odd-Electron Compounds a team of international experts provide a broad-based overview of stable radicals, from the fundamental aspects of specific classes of stable neutral radicals to their wide range of applications including synthesis, materials science and chemical biology. Topics covered include: triphenylmethyl and related radicals polychlorinated triphenylmethyl radicals: towards multifunctional molecular materials phenalenyls, cyclopentadienyls, and other carbon-centered radicals the nitrogen oxides: persistent radicals and van der Waals complex dimers nitroxide radicals: properties, synthesis and applications the only stable organic sigma radicals: di-tert-alkyliminoxyls. delocalized radicals containing the hydrazyl [R2N-NR] unit metal-coordinated phenoxyl radicals stable radicals containing the thiazyl unit: synthesis, chemical, and materials properties stable radicals of the heavy p-block elements application of stable radicals as mediators in living-radical polymerization nitroxide-catalyzed alcohol oxidations in organic synthesis metal-nitroxide complexes: synthesis and magneto-structural correlations rechargeable batteries using robust but redox-active organic radicals spin labeling: a modern perspective functional in vivo EPR spectroscopy and imaging using nitroxides and trityl radicals biologically relevant chemistry of nitroxides Stable Free Radicals: Fundamentals and Applied Aspects of Odd-Electron Compounds is an essential guide to this fascinating area of chemistry for researchers and students working in organic and physical chemistry and materials science.

Oxidation reactions are an important chemical transformation in both academia and industry. Among the major advances in the field has been the development of catalytic processes, which are not only selective and efficient, but also allow the replacement of common stoichiometric oxidants with molecular oxygen, ideally from air at atmospheric pressure. This results in processes with higher atom efficiency, where water is the only side product in line with the principles of green chemistry. Focusing on the use of molecular oxygen as the terminal oxidant, this book covers recent advances in both heterogeneous and homogeneous systems, with and without metals and on the “taming” of the highly reactive oxygen gas by use of micro-flow reactors and membranes. A useful reference for industrial and academic chemists working on oxidation processes, as well as green chemists.

Elementary radical reactions are described in terms of fundamental knowledge of organic chemistry and chemical physics in this valuable reference text. The complex radical processes of nonchain and chain mechanisms, such as dimerization, alkylation, polymerization, telomerization, halogenation pyrolysis, oxidation and combustion, are complemented by reactions in chemical lasers and in the cosmos, as well as by reactions in biological objects under normal or pathological metabolism. The text also provides the synthesis of facts from various fields of research and involves mechanisms where free radicals appear either as main or side intermediates in one of the several alternatives of the reaction pathway. Highlights include 38 tables and 39 figures.

In recent years, the rapid development of organic radical-containing materials has afforded an interesting research area in various applications. - Covers the main proprieties and current techniques in organic radicals' measurements, advantages, and disadvantages - Analyzes the lifecycle analysis and the stability of organic radicals, their biodegradability, and biocompatibility - Provides a comprehensive overview about the chemical synthesis of organic radicals, their physiochemical proprieties, and risks caused by the presence of high amounts of organic radicals

Our understanding of the quantitative aspects of free radical chemistry and the involvement of radicals in such areas as biology, medicine, the environment, etc., has developed spectacularly over recent years, yet the various topics are commonly discussed separately, in specific meetings and specialised publications. Free Radicals in Biology and Environment draws together two important areas of free radical chemistry, using as a bridge the fundamental physical chemistry of free radicals (spectroscopic detection of free radicals, evaluation of absolute rate constants, elucidation of mechanisms of free radical reactions and catalysis, photochemical and radiation processes, etc.). The most relevant topics covered are the EPR detection of radicals in biochemical systems and in pollutant formation and degradation, oxidation processes in biology and in the troposphere, radiation and induced damage, and atmospheric pollutants arising from incomplete combustion. Also covered are the chemistry and biochemistry of nitric oxide and peroxynitrite, the chemistry and biochemistry of DNA radicals, the role of radicals in myeloperoxidase, lignineperoxidase, radicals and cardiovascular injury, radiation and the fragmentation of cells and tissues.

This book commences with a general introduction outlining the basic concepts of radical polymerization. This is followed by a chapter on radical reactions that is intended to lay the theoretical ground-work for the succeeding chapters on initiation, propagation and termination.

In the short time since the first nitroxyl radical was obtained in 1959, a new branch of chemical science has arisen and taken shape-the chemistry of stable nitroxyl radicals. The present book was written by E. G. Rozantsev, one of the pioneers in this field and a prominent specialist on stable radicals at the Division of Chemical and Biological Processes of the Institute of Chemical Physics, Academy of Sciences of the USSR. His numerous papers have contributed greatly to the present situation, wherein nitroxyl radicals have acquired unusually wide popularity, including the fields of biology, medicine, chemis try, physics, biophysics, and instrument construction. A clear illustration of the astonishingly vigorous development of this new field of chemistry can be given by the enormous flow of information on the synthesis and use of nitroxyl radicals. There is no doubt that this monograph, which in part generalizes the results of many workers studying these radicals, will be received with interest by specialists working in this field. The author has not attempted to give an exhaustive account of the material. His aim is to introduce the reader to this new field and to show the wide possibilities for using radicals in scientific experiment. The voluminous bibliography, including many papers by the author himself which may not be well enough known to the American reader, will undoubtedly contribute to the usefulness of the monograph.
