These volumes are the latest in a series covering the expanding body of work in the field of organic chemistry. Reflecting the ideas of individual contributors, they provide a forum for the exchange of views through critical and authoritative reviews of a wide range of current topics. Each topic is presented in a style that is not only more speculative but also provides more detailed coverage than that found in textbooks. Appropriate to this quantitative approach to the subject, citation of numerical data is widely incorporated into the material.
