The Art of Writing Reasonable Organic Reaction Mechanisms

by Robert B. Grossman

Overview

Intended for students of intermediate organic chemistry, this text shows how to write a reasonable mechanism for an organic chemical transformation. The discussion is organized by types of mechanisms and the conditions under which the reaction is executed, rather than by the overall reaction as is the case in most textbooks. The treatment emphasizes unifying principles, showing how common mechanisms link seemingly disparate reactions.

Each chapter discusses common mechanistic pathways and suggests practical tips for drawing them. Worked problems are included in the discussion of each mechanism, and “common error alerts” are scattered throughout the text to warn readers about pitfalls and misconceptions that bedevil students. Each chapter is capped by a large problem set.

The author has drawn on his own research and the current literature to ensure that appropriate attention is given to topics across the range of modern organic chemistry. The text is unique inits inclusion of a chapter on reactions mediated or catalyzed by transition metals, an area in which mechanistic understanding is now essential. More modern topics such as olefin metathesis and cycloaromatization are covered without giving short shrift to more traditional areas such as carbonyl chemistry. The text assumes a basic knowledge of organic chemistry. It can be used either in a formal course or by students working on their own, and will be particularly useful for graduate students studying for qualifying examinations. It will also be useful to students and researchers in biochemistry, pharmacology, and inorganic chemistry.

The third edition includes greater discussion of the reactions of biological cofactors such as thiamine and pyridoxal, and discussions of modern developments such as metal-catalyzed C–H activation reactions have been added. In terms of stylistic improvements, the author has introduced color into drawings to improve visual clarity and has improved the depictions of radical anions and radical chain reactions.

Introduction

The purpose of The Art of Writing Reasonable Organic Reaction Mechanisms is to teach you how to write reasonable organic reaction mechanisms for synthetically useful organic and organometallic reactions. Rather than telling you the "right" mechanism for every possible reaction and expecting you to memorize it, I try to show you how to puzzle through a problem to arrive at a reasonable mechanism.

The book is organized by mechanistic types. The first chapter covers such fundamental concepts as formal charges, curved-arrow formalisms, acidity and basicity, nucleophilicity and electrophilicity, and methods for identifying which of the five classes of mechanisms is operative in a particular reaction. The following five chapters cover polar reactions under basic conditions, polar reactions under acidic conditions, pericyclic reactions, free-radical reactions, and metal-mediated and -catalyzed reactions, and the final chapter consists of a mix of problems. Each chapter discusses and provides examples of common mechanistic pathways. In addition to problems scattered throughout the text, a very large problem set is found at the end of the chapter; the answers are available for free from the publisher's Web site.

The "Common Error Alerts" are a unique feature of this book. A reasonable mechanism is simply one in which no step is unreasonable, so if you can learn what not to do when drawing a mechanism, you will be well ahead of the game. The Common Error Alerts are scattered throughout the text, warning you of common pitfalls and pointing out how to avoid them.

The Art of Writing Reasonable Organic Reaction Mechanisms book can be used as a textbook for advanced undergraduates or beginning graduate students. It will be especially valuable to beginning graduate students who are struggling through their cumes (written qualifying examinations). The book will be useful not only to chemistry students, but also to students in allied fields such as biochemistry, medicinal chemistry, and pharmacy.

Editorial Reviews

From the reviews of the second edition:

"… Grossman’s book differs from others in the scale of the worked examples. The number of problems incorporated into the text is extraordinary. The author provides the student a Web site that includes the detailed mechanisms for every problem in the book, each of which includes explanation and commentary, and the answer set, when printed, exceeds 250 pages! . . . In style, The Art of… is unique in that it does not read like a typical textbook. Instead, the feel is like that of having a personal tutor next to you walking you through the chemistry in a step-by-step fashion. The writing is clear, concise, engaging, and, at times, outright entertaining. The lively style includes "Common Error Alerts" that teach students what not to do and includes tips and advice on how to solve problems . . . The highest compliment a reviewer can give is to adopt the text that he reviews. The next advanced course I teach will use The Art of Writing Reasonable Reaction Mechanisms with the goal that students will be able to posit a plausible mechanism for any new reaction that they encounter. To those of you who have taught traditional physical organic chemistry out of the classic texts, I ask you to consider trying something, well… completely different. The Art of Writing Reasonable Reaction Mechanisms might just change the way you do things."

-Journal of Chemical Education

"The Art of Writing Reasonable Organic Reaction Mechanisms has an entirely different scope, dedicated to teaching the application of first principles to the construction of organic mechanisms. … The number of problems incorporated into the text is extraordinary. The author provides the student a Web site that includes the detailed mechanisms for every problem in the book … . The writing is clear, concise, engaging and, at times, outright entertaining. … All sections are expertly written, well organized andup-to-date." (R. W. Holman, Journal of Chemical Education, Vol. 80 (11), 2003)

"In principle, most mechanisms are derived from a basis set of fundamental steps. … Grossman has succeeded in explaining these fundamentals in detail in an easily accessible monograph. … Readers can reinforce their incipient skills with practical illustrations, and are challenged throughout with complicated examples. … the present text offers additional lucid explanations and ideal opportunities for practice. This work will thus be indispensable for students who are interested in mechanisms, or who wish to gain an additional perspective." (www.organische-chemie.ch, July, 2004)

"This text shows how to write a reasonable mechanism for an organic chemical transformation. … It can be used either in a formal course or by students working on their own, and will be particularly useful for graduate students studying for qualifying examinations. It will also be useful to students and researchers in biochemistry, pharmacology, and inorganic chemistry." (Chimie Nouvelle, Vol. 84 (21), 2003)

"Robert Grossman in his book attempts to familiarize the student with the awesome power of reaction mechanisms … . What makes this book special and praise-worthy is the clarity of its presentation of the subject matter. The text is lucid and sharp-edged throughout. The production quality of the book is first-class, too. Paper, printing and binding are excellent, the reproduction of the numerous formulae and reaction schemes is outstanding. … Full marks for this ‘survival guide’ to the ‘organic jungle’." (T. Lazar, Synthesis, Issue 17, 2003)
