Most syntheses in the chemical research laboratory fail and usually require several attempts before proceeding satisfactorily. Failed syntheses are not only discouraging and frustrating, but also cost a lot of time and money. Many failures may, however, be avoided by understanding the structure–reactivity relationship of organic compounds.

This advanced textbook highlights the competing processes and limitations of the most important reactions used in organic synthesis. By allowing chemists to quickly recognize potential problems this book will help to improve their efficiency and success–rate. A must for every student but also for every chemist in industry and academia.

"...I enjoyed reading this book and will refer to it often to help understand problem reactions. Highly recommended..."

Organic Process Research & Development

"The text in this book is clear, and the diagrams are well presented. There are lots of references, with titles making it easier for the reader to access the value of a reference before they go to find it. The author has worked hard on this book and made a brave effort. Overall, though, it is one for research libraries, but does not merit a personal investment, in my opinion."

Journal of the American Chemical Society

"The book should be required reading for all who believe that making molecules is an easy task. If, after reading it, they still consider that our organic synthesis is a worked–out branch of science, they must go to the laboratory and try to do it themselves."
