Introduction To Organic Photochemistry

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.

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. Includes experimental techniques to encourage novices Emphasizes topics where structural transformations can be formulated chemically Collects and presents practical applications Written in a simple style including enough examples to serve as an introduction to the diversity of photochemical reactions

In the decade after this book first appeared in 1974, research involving organic photochemistry was prolific. In this updated and expanded 1986 edition the authors summarise those classes of reaction that best illustrate the types of photochemical behaviour commonly observed for simple organic molecules. The different products obtained from compounds subjected to thermal and photolytic activation are explained with the aid of appropriate diagrams and mechanistic schemes. Where necessary, these are backed up by simple energy level profiles. Thus, theory and empirical data are interwoven to provide a firm basis which is aided by the generous basic references at the end of each chapter.

Photochemistry of Organic Compounds: From Concepts toPractice provides a hands-on guide demonstrating the underlyingprinciples of photochemistry and, by reference to a range oforganic reaction types, its effective use in the synthesis of neworganic compounds and in various applications. The book presents a complete and methodical approach to thetopic, Working from basic principles, discussing key techniques andstudies of reactive intermediates, and illustrating syntheticphotochemical procedures. Incorporating special topics and case studies covering variousapplications of photochemistry in chemistry, environmentalsciences, biochemistry, physics, medicine, and industry. Providing extensive references to the original literature andto review articles. Concluding with a chapter on retrosynthetic photochemistry,listing key reactions to aid the reader in designing their ownsynthetic pathways. This book will be a valuable source of information andinspiration for postgraduates as well as professionals from a widerange of chemical and natural sciences.

Photochemistry: An Introduction covers topics such as industrial photochemistry, solid state photochemistry, spectroscopy and photochemistry of the solid state, industrial applications of photochemistry, and photochromism. The book discusses the application of bonding, structure, energetics, and reactivity of the ground states of molecules to describe the same properties for molecules in their electronically excited states; the electronic spectra of excited states; and how the excited states react to form chemical transients. The text also describes light sources, techniques for measuring light intensities and quantum yields, methods used to detect transient photochemical products, and some ancilliary techniques. A review of some features of typical photochemical processes conducted in the vapor state and a survey of the reactions of the urban atmosphere, are also considered. The book further tackles the mechanisms of organic photochemical reactions; the synthetic applications of organic photochemistry; and the photochemistry of the solid state. The text also looks into photochromism and the industrial applications of photochemistry. People involved in the field of photochemistry will find the book useful.

In the past fifteen years organic photochemistry has undergone a greater change and has stimulated more interest than probably any other area of organic chemistry. What has resulted is a population explosion, that is, an ever-increasing number of organic chemists are publishing important and exciting research papers in this area. Professor Bryce-Smith in the introduc tion to a recent volume of the Specialist Periodical Report (Photochemistry, Volume 6), which reviews the photochemical literature in yearly intervals, states that "the flood of photochemical literature is showing some signs of abatement from the high levels of two or three years ago .... " However, Volume 6 of that periodical contains 764 pages of excellent but very concise reviews. We expect the development of the mechanistic aspects of organic photo chemistry to continue at the present pace as new methods are developed to probe in increasing detail and shorter time scales the photochemical dynamics of both old and new photoreactions. Since photochemistry is no longer the sole domain of the specialist, it is relatively safe to predict a dramatic increase in the near future of the synthetic and industrial uses of organic photo chemistry .

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.
