Homolytic Aromatic Substitution deals with the theoretical aspects of homolytic aromatic substitution reactions. The effect of various kinds of free radicals on the substitution of atoms or groups (usually hydrogen) attached to aromatic nuclei is examined, and the preparative use of homolytic substitution reactions is also considered. This book is comprised of seven chapters and begins with an introduction to the general characteristics of homolysis, along with homolytic and heterolytic aromatic substitution. The discussion then turns to the various theoretical approaches used to rationalize aromatic substitution, particularly those that are germane to a consideration of the problems of orientation and reactivity in homolytic substitution. The following chapters explore homolytic arylation reactions, including those between aryl radicals and aromatic substrates; relative rates of arylation and partial rate factors for phenylation; the reaction mechanism underlying intramolecular arylation; and homolytic alkylation reactions. The final chapter deals with hydroxylation and some other substitution reactions such as benzoyloxylation, acetyloxylation, halogenation, amination and amidation, and mercuration. This monograph will be of interest to organic chemists.

Today, arylation methods are belonging to the most important reaction types in organic synthesis. Lutz Ackermann, a young and ambitious professor has gathered a number of top international authors to present the first comprehensive book on the topic. Starting from a historical review, the book covers hot topics like Palladium-catalyzed arylation of N-H and alpha-C-H-acidic Bonds, Copper-catalyzed arylation of N-H and O-H Bonds, direct arylation reactions, carbanion aromatic synthesis, arylation reactions of alkenes, alkynes and much more. This compact source of high quality information is indispensable to synthetic chemists and those working in the pharmaceutical and chemical industry.

Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued.

In this dissertation, Marie-Hélène Larraufie develops original radical and pallado-catalyzed methodologies to enable the synthesis of several classes of bioactive nitrogen-containing heterocycles. New radical cascades employing the N-acylcyanamide moiety offer straightforward routes to quinazolinones and guanidines, as well as new insights into the mechanism of homolytic aromatic substitutions. In parallel, Larraufie expands the scope of visible light photoredox catalysis to the ring opening of epoxides and aziridines, thus providing new sustainable alternatives for the generation of radicals. Furthermore, in a collaborative effort with the Catellani group, the author investigates dual palladium/norbornene catalysis. First, she develops a C-amination coupling variant of the Catellani reaction with unprotected amines which provides an expeditious route to phenanthridines. Then, she examines the influence of the chelating effect on Pd(IV) intermediates reactivity with the help of experimental studies and DFT calculations. The work in this thesis has resulted in numerous publications in high impact journals.The clarity and depth of the experimental section will be useful for students and researchers working in this field.

Tailored to the needs of medicinal and natural products chemists, the second edition of this unique handbook brings the contents up to speed, almost doubling the amount of chemical information with an additional volume. As in the predecessor, a short introductory section covers the theoretical background and evaluates currently available instrumentation and equipment. The main part of the book then goes on to systematically survey the complete range of published microwave-assisted synthesis methods from their beginnings in the 1990s to mid-2011, drawing on data from more than 5,000 reports and publications. Throughout, the focus is on those reactions, reagents and reaction conditions that work, and that are the most relevant for medicinal and natural products chemistry. A much expanded section is devoted to combinatorial, highthroughput and flow chemistry methods.

The only book series to summarize the latest progress on organic reaction mechanisms, Organic Reaction Mechanisms, 1990 surveys the development in understanding of the main classes of organic reaction mechanisms reported in the primary scientific literature in 1990. The 26th annual volume in this highly successful series highlights mechanisms of stereo-specific reactions. Reviews are compiled by a team of experienced editors and authors, allowing advanced undergraduates, graduate students, postdocs, and chemists to rely on the volume's continuing quality of selection and presentation.
