Examines the latest applications of photochemistry to generate important intermediatesPresenting the latest breakthroughs in the field of organic photochemistry, this book offers tested and proven photochemical approaches to synthesis, creating promising new possibilities and applications for photochemical reactions. It focuses on photoreactions involving an intermediate where mechanistic aspects control the course of the reaction and its synthetic value. Readers will discover new insights into the mechanisms and nature of photo-produced reactive intermediates for organic synthesis as well as the methods to generate them. Moreover, by focusing on highly efficient techniques for producing such species, the authors enable researchers to design and perform photoreactions within the framework of green, sustainable chemistry.Photochemically-Generated Intermediates in Synthesis begins with a discussion of the principles and practice of photo-generated intermediates. Next, the book explores: Photogeneration of carbon-centered radicalsPhotogeneration of heteroatom-centered radicalsPhotogeneration of biradicals and radical pairsPhotochemical generation of radical ionsPhotogeneration of carbocations and carbanionsPhotogeneration of carbenes and nitrenesThe book's final chapter is dedicated to the photochemical manipulation of intermediates. Each chapter includes key kinetic data for typical intermediates as well as detailed case examples, giving readers all the tools needed to perform their own photochemical reactions. Comparisons to non-photochemical methods are offered whenever possible.Photochemically-Generated Intermediates in Synthesis sets the stage for greater collaboration among photochemists and synthetic organic chemists, enabling these two research communities to fully leverage photochemistry in order to generate key intermediates needed for a broad range of synthetic reactions in organic chemistry.

The use of organocatalysts able to photocatalyze an organic reaction is a rapidly growing field. These photocatalyzed transformations are more environmentally sustainable with respect to the use of expensive/toxic metal-based (photo)catalysts.Based on the authors' extensive experience in photogenerated intermediates, this book presents an overview on photocatalyzed organic processes having a synthetic significance, where an organic molecule functions as the photocatalyst.After a brief introduction defining the nature and the characteristics of a photoorganocatalyst (POC), the chapters are organized according to the class of POC used, as detailed below.Each chapter begins with a summary of the photophysical characteristics of the POCs and is followed by selected examples of synthetic applications. The last two chapters are devoted to the adoption of photoorganocatalysis in polymerization and to flow photoorganocatalysis. These in-depth explanations and practical applications make this title an essential reading for any chemistry student interested in organic (sustainable) synthesis.

This issue of Photochemical & Photobiological Sciences is dedicated to Prof. Angelo Albini on the occasion of his 75th birthday. It includes original articles and reviews from colleagues, former students, but especially friends, from the (photo)chemical community. It is a pleasure to dedicate this issue to Angelo because of the great contributions he gave to the study of light-driven reactions and to the photogeneration of reactive intermediates to be used in synthesis and to the understanding of mechanisms involved in photoinduced processes. The beginning of his career has been devoted to the photochemistry of heterocycles (e.g. phenazines), then his innate curiosity and enthusiasm in facing new challenges pushed himself towards the study of different topics, including photoinduced electron (and hydrogen-atom) transfer, nitrenes and singlet oxygen chemistry, the photodegradation of drugs and the photogeneration of triplet phenyl cations. This issue is made by more than 35 papers virtually covering all photochemical topics, including photosensitization, photoinduced electron transfer, photocatalysis, photobiology, photodynamics, chemiluminescence, light-driven bond cleavage, photocycloaddition, photocaged molecules, helical compounds and reactive intermediates in environments with restricted diffusion (e.g. micelles, organic capsules). As an active part of the photochemistry community, we are indebted to the huge work Angelo developed during his career and we thank all the contributors for being part of this exciting project. Finally, we would like to thank Angelo, a special friend and a mentor for us, remembering that his scientific heritage is still alive in the PhotoGreen Lab at the University of Pavia. Grazie, Angelo!

Unique in its focus on preparative impact rather than mechanistic details, this handbook provides an overview of photochemical reactions classed according to the structural feature that is built in the photochemical step, so as to facilitate use by synthetic chemists unfamiliar with this topic. An introductory section covers practical questions on how to run a photochemical reaction, while all classes of the most important photocatalytic reactions are also included.Perfect for organic synthetic chemists in academia and industry.
