This English edition of a best-selling and award-winning German textbook Reaction Mechanisms: Organic Reactions A- Stereochemistry A- 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: ..". The strength of the book stems from Professor Brucknera (TM)s ability to provide lucid explanations based on a deep understanding of physical organic chemistry...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. ..."Alan C. Spivey, Imperial College London "Brucknera (TM)s a Organic Mechanismsa (TM) accurately reflects the way practicing organic chemists think and speak about organic reactions. 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 "a ]a superb book to put in the hands of all who would want to learn synthetic organic chemistry or refresh their knowledge."Paul Knochel, Ludwig-Maximilians-University Munich ..". This text is aimed squarely at students that have completed a typical one-year introductory course in organic chemistry and now wish to continue refining their understanding of the subject. It is a sound introduction to the underlying principles that control reactivity in variety of transformations. The book is particularly well suited for intermediate and advanced classes in organic chemistry. ..."Marc L. Snapper, Boston College "This is an excellent advanced organic chemistry textbook that provides a key resource for students and teachers alike."Mark Rizzacasa, University of Melbourne, Australia "Having held in high regard the 1st English edition of BrucknerAs textbook Organic Reaction Mechanisms I have been waiting for years for an updated version to appear. This long-expected textbook is now available. It has been completely revised and considerably expanded and is a meticulously composed treatise at the interface between synthetic organic chemistry and mechanistic analysis. Every student of advanced organic chemistry will benefit from this book."Koichi Narasaka, Nayang Technical University, Singapore
