This new volume in the Postgraduate Chemistry Series provides a thorough overview of the principles and uses of synthetic organic photochemistry. Appropriate at postgraduate and research level it will also serve as a reference for more experienced workers.

Organic Photochemistry outlines the principles, techniques and well-known reactions occurring in organic molecules and also illustrates more complex photochemical transformations occurring in organic chemistry. Many photochemical transformations convert simple molecules into extremely complex products with an ease not approached by the standard synthetic chemistry practiced in the laboratory. In the earlier chapters, the author outlines the principles, techniques and some of the well-known reactions occurring in organic molecules and later illustrates more complex photochemical transformations occuring in organic chemistry. Experimental techniques are included to encourage novices. Topics are emphasized where structural transformations can be formulated chemically. Practical applications are collected together. The book starts at a comfortably simple level with enough examples to provide an introduction to the diversity of photochemical reactions.

Of all major branches of organic chemistry, I think none has undergone such a rapid, even explosive, development during the past twenty-five years as organic photochemistry. Prior to about 1960, photochemistry was still widely regarded as a branch of physical chemistry which might perhaps have oc casional applications in the generation of free radicals. Strangely enough, this attitude to the subject had developed despite such early signs of promise as the photodimerization of anthracene first observed by Fritzsche in 1866, and some strikingly original pioneering work by Ciamician and Silber in the early years of this century. These latter workers first reported such varied photo reactions as the photoisomerization of carvenone to carvone camphor, the photodimerization of stilbene, and the photoisomerization of o-nitrobenzal dehyde to o-nitrosobenzoic acid; yet organic chemists continued for another fifty years or so to rely almost wholly on thermal rather than photochemical methods of activation in organic synthesis-truly a dark age. When my colleagues and I first began in the 1950s to study the synthetic possibilities of photoexcitation in the chemistry of benzene and its derivatives, virtually all the prior reports had indicated that benzene was stable to ultraviolet radiation. Yet I think it fair to say that more different types of photoreactions than thermal reactions of the benzene ring are now known. Comparable growth of knowledge has occurred in other branches of organic photochemistry, and photochemical techniques have in particular made possible or simplified the synthesis of numerous highly strained organic molecules.

Introduction to Organic Photochemistry John D. Coyle, The Open University, Milton Keynes The purpose of this book is to provide an introductory account of the major types of organic photochemical reactions, to enable those with a prior knowledge of basic organic chemistry to appreciate the differences between processes which occur photochemically (through an electronically excited state) and those that occur thermally (directly from the electronic ground state). The material is organized according to organic functional groups, in parallel with the approach adopted in most general textbooks on organic chemistry. In this respect it differs from many of the existing, older organic photochemistry texts. The first chapter provides an account of the distinctive features of photochemical reactions, and a physical/mechanistic framework for the descriptions in the rest of the book. The overall emphasis is on organic photoreactions potentially useful in synthesis. The book thus integrates this branch of chemistry with broader aspects of the subject, and introduces the reader to important applications of organic photochemistry.

(Abridged and translated) Organic photochemistry may be divided into three parts: theory which is the province of the physical chemist; instrumentation which requires the skill of both physicist and engineer; and preparation which falls within the sphere of the organic chemist. At one time the same person could cover all three fields without too much difficulty, but this has now become virtually impossible because the disciplines involved have expanded in both breadth and depth; it is there fore timely to have a separate treatment of preparative organic photo chemistry. There appears to be no review of the main photochemical reactions which includes the advances made in recent years available to the organic chemist working in the preparative field. An exception is the excellent "Photochemical Reactions" by C. R. MASSON, V. BOEKELHEIDE and W. A. NoYES JR., published in 1956, which gives a brief review of the reactions which are important in preparative organic photochemistry. The present monograph on the other hand seeks to provide a detailed survey for the chemist; the author does not set out to discuss every photo chemical reaction in the field of organic chemistry but he does include in addition to those of current interest in the preparative field some which are likely to be of interest in the future and which result in single end-products of known composition. The photochemical synthesis of highly polymerized products falls outside the scope of the work.

During the last two decades the photochemistry of organic molecules has grown into an important and pervasive branch of organic chemistry. In Modern Molecular Photochemistry, the author brings students up to date with the advances in this field - the development of the theory of photoreactions, the utilization of photoreactions in synthetic sequences, and the advancement of powerful laser techniques to study the mechanisms of photoreactions.
