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.

Neutral reactive intermediates -- radicals, carbenes, nitrenes, and aryenes -- occupy a fascinating place in the history of organic chemistry. First regarded as mere curiosities, neutral reactive intermediates ultimately came under the intense scrutiny of physical organic chemists from a mechanistic point-of-view. This concise text concentrates on how these electron-deficient species now play a key role in synthetic chemistry research. Important reactions are clearly and simply laid out with carefully chosen examples that illustrate their use in organic synthesis. Each chapter includes problems as well as suggestions for further reading. Undergraduates will find Reactive Intermediates an invaluable summary of this important topic in organic chemistry--one that fills a gap created by the superficial treatment accorded these valuable compounds in most chemistry textbooks.

Theoretical Aspects of Chemical Reactivity provides a broad overview of recent theoretical and computational advancements in the field of chemical reactivity. Contributions have been made by a number of leaders in the field covering theoretical developments to applications in molecular systems and clusters. With an increase in the use of reactivity descriptors, and fundamental theoretical aspects becoming more challenging, this volume serves as an interesting overview where traditional concepts are revisited and explored from new viewpoints, and new varieties of reactivity descriptors are proposed. Includes applications in the frontiers of reactivity principles, and introduces dynamic and statistical viewpoints to chemical reactivity and challenging traditional concepts such as aromaticity. * Written by specialists in the field of chemical reactivity * An authoritative overview of the research and progress * An essential reference material for students

Many controversial issues revolve around complex scientific arguments which can be better understood with at least a minimal knowledge and understanding of the chemical reactions and processes going on in the world around us. This textbook offers an accessible introduction to chemical principles and concepts, and applies them to relevant environmental situations and issues. Written for students who have not taken A' level chemistry, this book bridges the gap between GSCE chemistry and first year undergraduate level.

A range of alternative mechanisms can usually be postulated for most organic chemical reactions, and identification of the most likely requires detailed investigation. Investigation of Organic Reactions and their Mechanisms will serve as a guide for the trained chemist who needs to characterise an organic chemical reaction and investigate its mechanism, but who is not an expert in physical organic chemistry. Such an investigation will lead to an understanding of which bonds are broken, which are made, and the order in which these processes happen. This information and knowledge of the associated kinetic and thermodynamic parameters are central to the development of safe, efficient, and profitable industrial chemical processes, and to extending the synthetic utility of new chemical reactions in chemical and pharmaceutical manufacturing, and academic environments. Written as a coherent account of the principal methods currently used in mechanistic investigations, at a level accessible to academic researchers and graduate chemists in industry, the book is highly practical in approach. The contributing authors, an international group of expert practitioners of the techniques covered, illustrate their contributions by examples from their own research and from the relevant wider chemical literature. The book covers basic aspects such as product analysis, kinetics, catalysis, and investigation of reactive intermediates. It also includes material on significant recent developments, e.g. computational chemistry, calorimetry, and electrochemistry, in addition to topics of high current industrial relevance, e.g. reactions in multiphase systems, and synthetically useful reactions involving free radicals and catalysis by organometallic compounds.

Die Organische Chemie, die Welt des Kohlenstoffs, ist spannend, vielschichtig und manchmal auch ein wenig schwer zu verstehen. Dieses Buch ist das richtige für Sie, wenn Sie etwas mehr als nur die Grundlagen der Organik verstehen müssen und etwas tiefer in die Materie eindringen wollen. Sie erfahren, was Sie über Alkohole, Ether und Spektroskopie wissen sollten, was aromatische Verbindungen ausmacht, was es mit Carbonylen auf sich hat und vieles mehr. Auch kniffelige Themen wie Organometalle, Amine und Biomoleküle kommen nicht zu kurz. So bietet John T. Moore in diesem Buch einen leicht verständlichen Überblick über die etwas fortgeschrittenere Organische Chemie.

Wie funktionieren organische Reaktionen? Eine Frage, die sich jedem stellt, der mit Chemie zu tun hat. Grundlegendes Wissen über die Prinzipien organischer Reaktionsmechanismen ist unabdingbar, wenn man verstehen will, warum organische Moleküle so und nicht anders synthetisiert werden. Die 'Reaktionsmechanismen der Organischen Chemie' aus der Feder von Peter Sykes wurden weltweit über eine halbe Million mal verkauft. Sein neuestes erfolgreiches Werk über dieses stets hochaktuelle Thema liegt nun in der 2. Auflage vor und wendet sich besonders an 'Einsteiger' und alle, die ein grundlegendes Verständnis für organische Reaktionen erlangen wollen. Mit bewährtem didaktischen Geschick bringt er dem Leser die Grundprinzipien organischer Reaktionsmechanismen nahe. Leichtverständlich aber exakt geschrieben ist dieses Buch ein idealer Begleiter im Leistungskurs Chemie und für Chemiestudenten und -interessierte, die 'aufholen' wollen.

Currently there is no concise teaching text aimed at 2/3rd year undergraduates on organosulfur chemsitry. Organosulfur chemistry is widely taught at this level. After a brief introductory chapter the main part of the book deals with the preparation and chemical properties of the principal types of organosulfur compounds classified under the headings: Divalent sulfur compounds, Tricoordinate sulfur compounds, and Tetracoordinate sulfur compounds. In choosing examples to illustrate the text, the guiding principle has been that the illustrations should provide insight into and an understanding of the characteristic features of organosulfur chemistry. Two concluding chapters deal, on the one hand, with applications of organosulfur compounds in organic synthesis and, on the other, with a brief summary of organoselenium chemistry, highlighting the similarities and differences with respect to organosulfur chemistry.

In dem Lehrbuch für Studenten der Chemie werden wichtige Aspekte und Zusammenhänge der Strukturen anorganisch-chemischer Verbindungen dargelegt. Die Strukturmerkmale von Molekülverbindungen wie auch von Festkörpern werden behandelt und an anschaulichen Beispielen erläutert. So weit wie möglich werden diese Strukturen mit einfachen und eingängigen Theorien erklärt (Gillespie-Nyholm-Theorie, Ligandenfeldtheorie, Ionenradienverhältnisse, Pauling-Regeln, (8-N)-Regel u.ä.), es wird aber auch auf die moderne Bindungstheorie eingegangen. Wichtige Festkörperstrukturen werden wiederholte Male und dabei jedes Mal von einem anderen Standpunkt betrachtet. Zusammenhänge zwischen Struktur und physikalischen Eigenschaften werden herausgearbeitet.
