Download or read book Organic Mechanisms written by Reinhard Bruckner and published by Springer Science & Business Media. This book was released on 2010-01-20 with total page 873 pages. Available in PDF, EPUB and Kindle. Book excerpt: This English edition of a best-selling and award-winning German textbook Reaction Mechanisms: Organic Reactions · Stereochemistry · Modern Synthetic Methods is aimed at those who desire to learn organic chemistry through an approach that is facile to understand and easily committed to memory. Michael Harmata, Norman Rabjohn Distinguished Professor of Organic Chemistry (University of Missouri) surveyed the accuracy of the translation, made certain contributions, and above all adapted its rationalizations to those prevalent in the organic chemistry community in the English-speaking world. Throughout the book fundamental and advanced reaction mechanisms are presented with meticulous precision. The systematic use of red "electron-pushing arrows" allows students to follow each transformation elementary step by elementary step. Mechanisms are not only presented in the traditional contexts of rate laws and substituent effects but, whenever possible, are illustrated using practical, useful and state-of-the-art reactions. The abundance of stereoselective reactions included in the treatise makes the reader familiar with key concepts of stereochemistry. The fundamental topics of the book address the needs of upper-level undergraduate students, while its advanced sections are intended for graduate-level audiences. Accordingly, this book is an essential learning tool for students and a unique addition to the reference desk of practicing organic chemists, who as life-long learners desire to keep abreast of both fundamental and applied aspects of our science. In addition, it will well serve ambitious students in chemistry-related fields such as biochemistry, medicinal chemistry and pharmaceutical chemistry. From the reviews: "Professor Bruckner has further refined his already masterful synthetic organic chemistry classic; the additions are seamless and the text retains the magnificent clarity, rigour and precision which were the hallmark of previous editions. The strength of the book stems from Professor Bruckner’s ability to provide lucid explanations based on a deep understanding of physical organic chemistry and to limit discussion to very carefully selected reaction classes illuminated by exquisitely pertinent examples, often from the recent literature. The panoply of organic synthesis is analysed and dissected according to fundamental structural, orbital, kinetic and thermodynamic principles with an effortless coherence that yields great insight and never over-simplifies. The perfect source text for advanced Undergraduate and Masters/PhD students who want to understand, in depth, the art of synthesis ." Alan C. Spivey, Imperial College London "Bruckner’s ‘Organic Mechanisms’ accurately reflects the way practicing organic chemists think and speak about organic reactions. The figures are beautifully drawn and show the way organic chemists graphically depict reactions. It uses a combination of basic valence bond pictures with more sophisticated molecular orbital treatments. It handles mechanisms both from the "electron pushing perspective" and from a kinetic and energetic view. The book will be very useful to new US graduate students and will help bring them to the level of sophistication needed to be serious researchers in organic chemistry." Charles P. Casey, University of Wisconsin-Madison "This is an excellent advanced organic chemistry textbook that provides a key resource for students and teachers alike." Mark Rizzacasa, University of Melbourne, Australia.

Download or read book Reactive Intermediates in Organic Chemistry written by Maya Shankar Singh and published by John Wiley & Sons. This book was released on 2014-01-22 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Molecules from Side Reactions written by Stefano D’Errico and published by MDPI. This book was released on 2021-01-26 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Special Issue “Molecules from Side Reactions” is a collection of papers reporting on the synthesis and characterization of the molecules that come from unexpected synthetic routes. This is the first example of a Special Issue based on such a topic, notwithstanding that all synthetic chemists have isolated a side product during a chemical reaction. Instead of continuing to store the side products in the freezer, I have thought to give them the dignity of publication, making them available to the scientific community. The short manuscripts collected here respect the principle of “one compound per paper” and have the purpose of preserving the molecular diversity deriving from a chemical reaction. The molecular scaffolds are unexpected and intriguing, and could be useful starting points or intermediates for exploring novel reactions.
