Book Description
The explosive growth of organoselenium chemistry over the past 12 years can be attributed to the specific properties of organic selenium molecules, which fit the requirements of modern organic synthesis. Most of them are well adapted to chemo-, regio- and stereo-selectivities. In addition, they can be used in mild experimental conditions which are compatible with the stability of both substrates and products in the preparation of unsaturated and functional complex molecules, especially in the field of natural products. This book describes and illustrates different synthetic routes to organic structures using selenium reagents or intermediates. The approach emphasizes that such transformations are simple, efficient and often carried out at room temperature. The scope ranges from the preparation of both inorganic and organic selenium reagents, through descriptions of structure, toxicity, biological aspects and nuclear magnetic resonance, to applications of specific selenium compounds in various syntheses including natural products and biologically active compounds.

Book Description
Most reactions in organic chemistry do not proceed in a single step but rather take several steps to yield the desired product. In the course of these multi-step reaction sequences, short-lived intermediates can be generated that quickly convert into other intermediates, reactants, products or side products. As these intermediates are highly reactive, they cannot usually be isolated, but their existence and structure can be proved by theoretical and experimental methods. Using the information obtained, researchers can better understand the underlying reaction mechanism of a certain organic transformation and thus develop novel strategies for efficient organic synthesis. The chapters are clearly structured and are arranged according to the type of intermediate, providing information on the formation, characterization, stereochemistry, stability, and reactivity of the intermediates. Additionally, representative examples and a problem section with different levels of difficulty are included for self-testing the newly acquired knowledge. By providing a deeper understanding of the underlying concepts, this is a musthave reference for PhD and Master Students in organic chemistry, as well as a valuable source of information for chemists in academia and industry working in the field. It is also ideal as primary or supplementary reading for courses on organic chemistry, physical organic chemistry or analytical chemistry.

Book Description
Aziridines and epoxides are among the most widely used intermediates in organic synthesis, acting as precursors to complex molecules due to the strains incorporated in their skeletons. Besides their importance as reactive intermediates, many biologically active compounds also contain these three-membered rings. Filling a gap in the literature, this clearly structured book presents the much needed information in a compact and concise way. The renowned editor has succeeded in gathering together excellent authors to cover synthesis, applications, and the biological aspects in equal depth. Divided roughly equally between aziridines and epoxides, the twelve chapters discuss: * Synthesis of aziridines * Nucleophilic ring-opening of aziridines and epoxides * Organic synthesis with aziridine building blocks * Vinyl aziridines in organic synthesis * Diastereoselective aziridination reagents * Synthetic aspects of aziridinomitocene chemistry * Biosynthesis of biologically important aziridines * Organic catalysis of epoxide and aziridine ring formation * Metal-mediated synthesis of epoxides * Asymmetric epoxide ring opening chemistry * Epoxides in complex molecule synthesis * Biological activity of epoxide-containing molecules A high-quality reference manual for academic and industrial chemists alike.

Book Description
Examines the latest applications of photochemistry to generate important intermediates Presenting the latest breakthroughs in the field of organic photochemistry, this book offers tested and proven photochemical approaches to synthesis, creating promising new possibilities and applications for photochemical reactions. It focuses on photoreactions involving an intermediate where mechanistic aspects control the course of the reaction and its synthetic value. Readers will discover new insights into the mechanisms and nature of photo-produced reactive intermediates for organic synthesis as well as the methods to generate them. Moreover, by focusing on highly efficient techniques for producing such species, the authors enable researchers to design and perform photoreactions within the framework of green, sustainable chemistry. Photochemically-Generated Intermediates in Synthesis begins with a discussion of the principles and practice of photo-generated intermediates. Next, the book explores: Photogeneration of carbon-centered radicals Photogeneration of heteroatom-centered radicals Photogeneration of biradicals and radical pairs Photochemical generation of radical ions Photogeneration of carbocations and carbanions Photogeneration of carbenes and nitrenes The book's final chapter is dedicated to the photochemical manipulation of intermediates. Each chapter includes key kinetic data for typical intermediates as well as detailed case examples, giving readers all the tools needed to perform their own photochemical reactions. Comparisons to non-photochemical methods are offered whenever possible. Photochemically-Generated Intermediates in Synthesis sets the stage for greater collaboration among photochemists and synthetic organic chemists, enabling these two research communities to fully leverage photochemistry in order to generate key intermediates needed for a broad range of synthetic reactions in organic chemistry.

Book Description
Organic chemistry is a core part of the chemistry curricula, andadvanced levels texts often obscure the essential frameworkunderlying and uniting the vast numbers of reactions as a result ofthe high level of detail presented. The material in this book iscondensed into a manageable text of 350 pages and presented in aclear and logical fashion, focusing purely on the basics of thesubject without going through exhaustive detail or repetitiveexamples. The book aims to bridge the gap between undergraduateorganic chemistry textbooks and advanced level textbooks, beginningwith a basic introductory course and arranging the reactionmechanisms according to an ascending order of difficulty. As such,the author believes the book will be excellent primer for advancedpostgraduates Reaction Mechanisms in Organic Synthesis is written fromthe point of view of the synthetic organic chemist, enablingstudents and researchers to understand and expand on reactionscovered in foundation courses, and to apply them in a practicalcontext by designing syntheses. As a further aid to the practicalresearch student, the content is organized according to theconditions under which a reaction is executed rather than by thetypes of mechanisms. Particular emphasis is placed on controllingstereospecificity and regiospecificity. Topics covered include: Transition metal mediated carbon-carbon bond formationreactions Use of stabilized carbanions, ylides and enamines forcarbon-carbon bond formation reactions, Advanced level use of oxidation and reduction reagents insynthesis. As a modern text, this book stands out from its competitors dueto its comprehensive coverage of recently published research. Thebook contains specific examples from the latest literature,covering modern reactions and the latest procedural modifications.The focus on contemporary and synthetically useful reactionsensures that the contents are specifically relevant and attractiveto postgraduate students and industrial organic chemists.
