This book describes the fascinating chemistry of the many kinds of organic compounds of hypervalent iodine. Each chapter deals with a particular iodine compound or families of compounds which have been used as reagents in a plethora of useful transformations. These include assorted oxidation, such as with the precious Dess-Martin reagent as well as with a wide range of further reactions.
Prominent features of hypervalent iodine reagents derived from iodobenzene are: ready availability, operational simplicity, mild reaction conditions, and high efficiency. They are environmentally safe and can be recycled. New species may be easily prepared by introducing substituents in the benzene ring or changing the ligand attached to iodine. Their combination with other reagents broadens considerably their synthetic potential. Today, no synthetic chemist can afford to ignore the valuable hypervalentiodine reagents.
Key Features
* Features up-to-date coverage of a wide range of topics
* Includes many tables featuring a diversity of reactivity, and a comprehensive index
* Acts as a comprehensive, up-to-date reference on all aspects of hypervalent iodine chemistry
* Contains a section on unusual efficiency of hypervalent iodine reactions

Advances in Heterocyclic Chemistry, Volume 103, deals with the organic chemistry of heterocyclic compounds, namely, photochromic dihetarylethenes, pyrido[1,2-a]azepines and their hydro derivatives, and 2-amino-4H-pyrans. Divided into three chapters, the book examines advances in the synthesis of these three compounds, including dithienylethenes that are derived from photochemically induced isomerizations between the cis- and trans-forms and cyclized derivatives. The book first looks at the synthesis of photochromic dihetarylethenes, such as perfluorocyclopentene-bridged dihetarylethenes, along with dithienylperhydrocyclopentenes and their heteroanalogs, like perhydrocyclopentenes, dithienylmaleic anhydrides, and dithienylmaleimides. It then discusses the McMurry reaction and the reactions between octafluorocyclopentene and lithium derivatives of thiophene. It also examines chemistry, structure, reactivity, and the pharmaceutical and agrochemical uses of of pyrido[1,2-a]azepines and their hydro derivatives. The book concludes with a summary of the synthesis, structure, reactivity, and practical significance of 2-amino-4H-pyrans. This book will benefit graduate students and research workers in academic and industrial laboratories who want to gain a better understanding of heterocyclic chemistry.

Die entsprechenden Dbersichten in Kapitel 4 findet man in den Abschnitten 4.II, 4.II1 und 4.IV. 2. Grundlagen der Elektronentheorie der organischen Chemie* Die organische Chemie hat sich heute so weit entwickelt, daB man die groBe Mehrzahl aller Reaktionen durch eine Aufeinanderfolge einzelner Schritte erklaren und korrelieren kann, wobei sich diese Schritte ihrer- seits in wenige einfache, grundlegende Reaktionstypen unterteilen lassen. Bei jeder organischen Reaktion werden Bindungen gel6st und/oder gebildet. Eine chemische Bindung besteht aus zwei Elektronen, die zwei Atomen gemeinsam angeh6ren, und sie wird gebildet (oder ge16st) auf dreierlei Weise: 1. Eines der beiden Atome tragt beide Elektronen zur Bindung bei, entweder von einem einsamen Elektronenpaar oder von einer anderen Bindung, haufig einer Mehrfachbindung (die gekriimmten Pfeile deuten die Verschiebung eines Elektronenpaares an). Die Atome erhalten dabei form ale Ladungen. Reaktionen dieses Typs, die man verallgemeinert "ionische Reaktionen" nennt, sind die bei weitem wichtigsten. Das Atom, Molekiil oder Ion, welches das Elektronenpaar liefert, wird als nuc1eophiles Reagens bezeichnet und dasjenige, welches die Elektronen empfangt, als elektrophiles Reagens. 2. Jedes Atom tragt ein Atom zur Bindung bei (wobei die punktierten Pfeile die Verschiebung eines einzelnen Elektrons andeuten). Reaktionen dieses Typs sind als radikalische Reaktionen bekannt, denn mindestens einer der Reaktionspartner oder Reaktions- produkte muB ein freies Radikal sein, d. h. ein ungepaartes Elektron enthalten.
