Nucleophilic aromatic substitution in carbo- and heteroaromatic systems is a subject of considerable interest to chemists. This book uniquely addresses the systematic analysis of a vast range of nucleophilic substitutions of aromatic hydrogen. * This text provides coverage of: * Nucleophilic displacement of hydrogen (the S N/H reactions) in pi-deficient aromatics, such as nitroarenes, arene-metal complexes, and the like. * Nucleophilic displacement of hydrogen in heterocyclic substrates such as pyridines, their aza and benzo analogs, pyrylium and thiapyrylium cations, and other heterocycles * Mechanisms for the S N/H reactions (S N/H(AE), vicarious nucleophilic substitutions, and radical S N/H substitutions

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.

Ein neuer Stern am Lehrbuch-Himmel: Organische Chemie von Clayden, Greeves, Warren - der ideale Begleiter für alle Chemiestudenten. Der Schwerpunkt dieses didaktisch durchdachten, umfassenden vierfarbigen Lehrbuches liegt auf dem Verständnis von Mechanismen, Strukturen und Prozessen, nicht auf dem Lernen von Fakten. Organische Chemie entpuppt sich als dabei als ein kohärentes Ganzes, mit zahlreichen logischen Verbindungen und Konsequenzen sowie einer grundlegenden Struktur und Sprache. Dank der Betonung von Reaktionsmechanismen, Orbitalen und Stereochemie gewinnen die Studierenden ein solides Verständnis der wichtigsten Faktoren, die für alle organisch-chemischen Reaktionen gelten. So lernen sie, auch Reaktionen, die ihnen bisher unbekannt waren, zu interpretieren und ihren Ablauf vorherzusagen. Der direkte, persönliche, studentenfreundliche Schreibstil motiviert die Leser, mehr erfahren zu wollen. Umfangreiche Online-Materialien führen das Lernen über das gedruckte Buch hinaus und vertiefen das Verständnis noch weiter.
