Download or read book Homolytic Aromatic Substitution written by G. H. Williams and published by Elsevier. This book was released on 2014-04-08 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Aromatic and Heteroaromatic Chemistry written by C W Bird and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Development of New Radical Cascades and Multi Component Reactions written by Marie-Helene Larraufie and published by Springer Science & Business Media. This book was released on 2013-12-16 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Modern Nucleophilic Aromatic Substitution written by Francois Terrier and published by John Wiley & Sons. This book was released on 2013-05-20 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of nucleophilic aromatic substitutions, focusing on the mechanistic and synthetic features that govern these reactions. The first chapter presents a detailed mechanistic analysis of the factors determining the feasibility of SNAr substitutions, providing decisive information to predict regioselectivity of many reactions and to define the conditions for concerted SNAr processes. Reflecting the key role played by these species as intermediates in most SNAr reactions, chapter 2 then discusses the chemistry of anionic sigma-complexes. Chapter 3 describes the concept of superelectrophilicity in SNAr substitutions, as it has recently emerged from the reactivity of strongly electron-deficient aromatic and heteroaromatic structures. The numerous synthetic applications are considered in depth in the chapters 4 and 5 that follow on intermolecular and intramolecular nucleophilic aromatic substitutions. Then, chapter 6 focuses on substitutions proceeding formally through displacement of a hydride ion, a hot topic in the field. The final chapter brings together concise yet comprehensive discussions surrounding SNAr photosubstitutions, radical substitutions, and ANRORC substitutions. Authored by a highly respected chemist who has contributed greatly to the field over the past two decades, this is a valuable information source for all organic chemists working in academia or the pharmaceutical and agrochemical industries.

Download or read book Reactive Intermediates written by R.A. Abramovitch and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of reactive intermediates has been blossoming at a rapid rate in recent years and its impact on chemistry, both "pure" and "applied," as well as on biology, astronomy, and other areas of science, is enormous. Several books have been published which cover the area; one, edited by McManus, * surveys the subject in general at the senior undergraduate or beginning graduate level. In addition, a number of monographs have appeared which deal with individual topics such as carbenes, nitrenes, free radicals, carbanions, carbenium ions, and so on, in great depth. Our objective is somewhat different. We hope that these Advances in . . . type of volumes will appear at irregular intervals of a year to 18 months each. We intend to publish up-to-date reviews in relatively new areas of the chemistry of reactive intermediates. These will be written by world authorities in the field, each one of whom will give the reader a current in-depth review of all aspects of the chemistry of each of these species. It is our plan that the subjects to be reviewed will cover not only organic chemistry but also inorganic, physical, bio-, industrial, and atmospheric chemistry. The volumes themselves, we hope, will end up being reasonably interdisciplinary, though this need not and probably will not be the case for the individual reviews.
Download or read book Index to Reviews Symposia Volumes and Monographs in Organic Chemistry written by Norman Kharasch and published by Elsevier. This book was released on 2013-10-22 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Index to Reviews, Symposia Volumes and Monographs in Organic Chemistry for the Period 1940-1960 presents a resume of published monographs, reviews, and symposia lectures in organic chemistry. The editors adopted the plan of listings by symposia volume or journal, backed up by the total subject and author indexes. In this way the user can readily locate a particular article through the author index or the subject index; or should he recall that an article appeared in a particular source, the chronological listing in that source can be scanned quickly. The Index gives a convenient overview of the accomplishments of organic chemists during this very prolific period of the growth of the field. Frequently, several articles on the same or similar subject appear, hence the historical perspective can be sensed by rapid evaluation of the reviews selected. This Index will be useful to research workers, teachers and students. It will also assist editors and authors to select specific areas which require critical review.
