Covers the most advanced computational and experimental methods for studying carbon-centered radical intermediates With its focus on the chemistry of carbon-centered radicals and radical cations, this book helps readers fully exploit the synthetic utility of these intermediates in order to prepare fine chemicals and pharmaceutical products. Moreover, it helps readers better understand their role in complex atmospheric reactions and biological systems. Thoroughly up to date, the book highlights the most advanced computational and experimental methods available for studying and using these critically important intermediates. Carbon-Centered Free Radicals and Radical Cations begins with a short history of the field of free radical chemistry, and then covers: A discussion of the relevant theory Mechanistic chemistry, with an emphasis on synthetic utility Molecular structure and mechanism, focusing on computational methods Spectroscopic investigations of radical structure and kinetics, including demonstrations of spin chemistry techniques such as CIDNP and magnetic field effects Free radical chemistry in macromolecules Each chapter, written by one or more leading experts, explains difficult concepts clearly and concisely, with references to facilitate further investigation of individual topics. The authors were selected in order to provide insight into a broad range of topics, including small molecule synthesis, polymer degradation, computational chemistry as well as highly detailed experimental work in the solid, liquid, and gaseous states. This volume is essential for students or researchers interested in building their understanding of the role of carbon-centered radical intermediates in complex systems and how they may be used to develop a broad range of useful products.

Free radical reactions have become increasingly important and a very attractive tool in organic synthesis in the last two decades, due to their powerful, selective, specific, and mild reaction abilities. Advanced Free Radical Reactions for Organic Synthesis reviews information on all types of practical radical reactions, e.g. cyclizations, additions, hydrogen-atom abstractions, decarboxylation reactions. The book usefully provides experimental details for the most important reactions as well as numerous references to the original literature. By covering both the fundamentals and synthetic applications it is therefore suitable for both new and experienced researchers, chemists, biochemists, natural product chemists and graduate students. This title is the definitive guide to radical chemistry for all scientists. Introduces and reviews the use of radicals to perform synthetic transformations Practical details are provided for the most important methods Numerous references to the original literature

The free-radical chemistry of DNA had been discussed in some detail in 1987 in my book The Chemical Basis of Radiation Biology. Obviously, the more recent developments and the concomitant higher level of understanding of mechanistic details are missing. Moreover, in the living cell, free-radical DNA damage is not only induced by ionizing radiation, but free-radical-induced DNA damage is a much more general phenomenon. It was, therefore, felt that it is now timely to review our present knowledge of free-radical-induced DNA damage induced by all conceivable free-radical-generating sources. Originally, it had been thought to include also a very important aspect, the repair of DNA damage by the cell’s various repair enzymes. Kevin Prise (Cancer Campaign, Gray Laboratory, L- don) was so kind to agree to write this part. However, an adequate description of this strongly expanding area would have exceeded the allocated space by much, and this section had to be omitted. The directors of the Max-Planck-Institut für Strahlenchemie (now MPI für Bioanorganische Chemie), Karl Wieghardt and Wolfgang Lubitz, kindly allowed me to continue to use its facilities after my retirement in 2001. Notably, our - brarian, Mrs. Jutta Theurich, and her right-hand help, Mrs. Rosemarie Schr- er, were most helpful in getting hold of the literature. I thank them very much. Without their constant help, this would have been very difficult indeed.

The use of antioxidants in sports is controversial due to existing evidence that they both support and hinder athletic performance. Antioxidants in Sport Nutrition covers antioxidant use in the athlete ́s basic nutrition and discusses the controversies surrounding the usefulness of antioxidant supplementation. The book also stresses how antioxidants may affect immunity, health, and exercise performance. The book contains scientifically based chapters explaining the basic mechanisms of exercise-induced oxidative damage. Also covered are methodological approaches to assess the effectiveness of antioxidant treatment. Biomarkers are discussed as a method to estimate the bioefficacy of dietary/supplemental antioxidants in sports. This book is useful for sport nutrition scientists, physicians, exercise physiologists, product developers, sport practitioners, coaches, top athletes, and recreational athletes. In it, they will find objective information and practical guidance.
