vii PREFACE It has been almost a quarter of a century since the first edition of our book The Vocabulary of Organic Chemistry was published. Like the vocabulary of every living language, old words remain, but new ones emerge. In addition to the new vocabulary, other important changes have been incorporated into this second edition. One of the most obvious of these is in the title, which has been expanded to The Vocabulary and Concepts of Organic Chemistry in recognition of the fact that in addressing the language of a science, we found it frequently necessary to define and explain the concepts that have led to the vocabulary. The second change from the first edition is authorship. Three of the original authors of the first edition have participated in this new version; the two lost collaborators were sorely missed. Professor Hans Zimmer died on June 13, 2001. His contribution to the first edition elevated its scholarship. He had an enormous grasp of the literature of organic chemistry and his profound knowledge of foreign languages improved our literary grasp. Professor Fred Kaplan also made invaluable contributions to our first edition. His attention to small detail, his organizational expertise, and his patient examination of the limits of definitions, both inclusive and exclusive, were some of the many advantages of his co-authorship. We regret that his other interests prevented his participation in the present effort. However, these unfortunate losses were more than compensated by the addition of a new author, Professor Allan Pinhas, whose knowledge, enthusiasm, and matchless energy lubricated the entire process of getting this edition to the publisher. Having addressed the changes in title and authorship, we need to describe the changes in content. Two major chapters that appeared in the first edition no longer appear here: “Named Organic Reactions” and “Natural Products.” Since 1980, several excellent books on named organic reactions and their mechanisms have appeared, and some of us felt our treatment would be redundant. The second deletion, dealing with natural products, we decided would better be treated in an anticipated second volume to this edition that will address not only this topic, but also the entire new emerging interest in biological molecules. These deletions made it possible to include other areas of organic chemistry not covered in our first edition, namely the powerful spectroscopic tools so important in structure determination, infrared spectroscopy, NMR, and mass spectroscopy, as well as ultraviolet spectroscopy and photochemistry. In addition to the new material, we have updated material covered in the first edition with the rearrangement of some chapters, and of course, we have taken advantage of reviews and comments on the earlier edition to revise the discussion where necessary. fpref.qxd 6/11/2005 9:31 AM Page vii
viii PREFACE The final important ques tion.we turn to the objective of the book.which is to identify the fundamental vocabulary and concepts of organic chemistry and present concise,accurate descrip- tions of them with examples when appropriate.It is not intended to be a dictionary but is organized into a sequence of chapters that reflect the way the subject is taught Related terms appear in close proximity to each other,and hence,fine distinct ons me understandable.Students and instructors may concentration ject matter into the essential a pects of the various topics overed.Inaddit we hope the book ill appeal toand prove useful to.many others in thech community who either in the recent past,or even remote past,were familiar with the topics defined,but whose precise knowledge of them has faded with time. In the course of writing this book,we drew generously from published books and articles,and we are grateful to the many authors who unknowingly contributed their expertise.We have also taken advantage of the special knowledge of some of our colleagues in the Department of Chemistry and we acknowledge them in appropri ate chapters MILTON ORCHIN ROGER S.MACOMBER ALLAN R.PINHAS R.MARSHALL WILSON
viii PREFACE The final item that warrants examination is perhaps one that should take precedence over others. Who should find this book useful? To answer this important question, we turn to the objective of the book, which is to identify the fundamental vocabulary and concepts of organic chemistry and present concise, accurate descriptions of them with examples when appropriate. It is not intended to be a dictionary, but is organized into a sequence of chapters that reflect the way the subject is taught. Related terms appear in close proximity to each other, and hence, fine distinctions become understandable. Students and instructors may appreciate the concentration of subject matter into the essential aspects of the various topics covered. In addition, we hope the book will appeal to, and prove useful to, many others in the chemical community who either in the recent past, or even remote past, were familiar with the topics defined, but whose precise knowledge of them has faded with time. In the course of writing this book, we drew generously from published books and articles, and we are grateful to the many authors who unknowingly contributed their expertise. We have also taken advantage of the special knowledge of some of our colleagues in the Department of Chemistry and we acknowledge them in appropriate chapters. MILTON ORCHIN ROGER S.
