This book marks a significantly different approach to the subject. It has been designed specifically to offer a simpler and less sophisticated treatment of organic reaction mechanisms than that to be found in the Guidebook. It is based on three underlying principles: that there are three types of reaction - substitution, addition and elimination; that there are three types of reagent - nucleophiles, electrophiles and radicals; and that there are two effects - electronic and steric - through which the behaviour of a particular atom or group can be influenced by the rest of the molecule of which it is a constituent part. A Primer to Mechanism in Organic Chemistry is an essential resource for first- and second-year chemistry undergraduates and particularly, though not exclusively, those not then proceeding to further chemical study. It is also a useful reference for sixth-form students.

Organic chemistry is a core part of the chemistry curricula, and advanced levels texts often obscure the essential framework underlying and uniting the vast numbers of reactions as a result of the high level of detail presented. The material in this book is condensed into a manageable text of 350 pages and presented in a clear and logical fashion, focusing purely on the basics of the subject without going through exhaustive detail or repetitive examples. The book aims to bridge the gap between undergraduate organic chemistry textbooks and advanced level textbooks, beginning with a basic introductory course and arranging the reaction mechanisms according to an ascending order of difficulty. As such, the author believes the book will be excellent primer for advanced postgraduates Reaction Mechanisms in Organic Synthesis is written from the point of view of the synthetic organic chemist, enabling students and researchers to understand and expand on reactions covered in foundation courses, and to apply them in a practical context by designing syntheses. As a further aid to the practical research student, the content is organized according to the conditions under which a reaction is executed rather than by the types of mechanisms. Particular emphasis is placed on controlling stereospecificity and regiospecificity. Topics covered include: Transition metal mediated carbon-carbon bond formation reactions Use of stabilized carbanions, ylides and enamines for carbon-carbon bond formation reactions, Advanced level use of oxidation and reduction reagents in synthesis. As a modern text, this book stands out from its competitors due to its comprehensive coverage of recently published research. The book contains specific examples from the latest literature, covering modern reactions and the latest procedural modifications. The focus on contemporary and synthetically useful reactions ensures that the contents are specifically relevant and attractive to postgraduate students and industrial organic chemists.

Understanding the mechanisms of the reactions at transition metal sites is a key component in designing synthetic methods, developing industrial homogeneous catalysts, and investigating metalloenzymes. These mechanisms are therefore an essential part of undergraduate chemistry courses. This primer provides a broad-based, systematic guide to the fundamentals of transition-metal mechanistic chemistry, including substitution, electron transfer, and reactions of ligands. It serves as an ideal text for undergraduate students with a foundation in basic inorganic chemistry but who are new to inorganic reaction mechanisms.

Organic Reaction Mechanisms shows readers how to interpret the experimental data obtained from an organic reaction, and specifically how an organic reaction mechanism can be considered or rejected based on the analysis of the experimental evidence. Whilst examining a series of selected examples of mechanisms, the text focuses on real cases and discusses them in detail. The examples are arranged to elucidate key aspects of organic reaction mechanisms. The authors employ all the types of information that the authors of the original work considered useful and necessary, including spectroscopic data, kinetic and thermodynamic data, isotopic labelling and organic reactivity. The book makes an excellent primer for advanced undergraduates in chemistry who are preparing for exams and is also useful for graduate students and instructors.

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.
