Die Katalyse ist als grundlegendes Prinzip zur Überwindung der kinetischen Hemmung chemischer Reaktionen von fundamentaler Bedeutung in der Chemie und die metallorganische Komplexkatalyse ist ein Eckpfeiler der modernen Chemie. Das trifft gleichermaßen für die Grundlagen- und angewandte Forschung wie für industrielle Anwendungen zu. Ausgehend von den Prinzipien der Katalyse und den katalytisch relevanten metallorganischen Elementarschritten werden wichtige metallkomplexkatalysierte Reaktionen behandelt, wobei das mechanistische Verständnis im Vordergrund steht. Besonderer Wert wird dabei auf aktuelle Entwicklungen gelegt. Asymmetrische Synthesen finden ausführlich Berücksichtigung und an ausgewählten Beispielen wird die katalytische Wirkung von Metalloenzymen aufgezeigt. Am Beispiel der Stickstofffixierung werden die drei großen Gebiete der Katalyse – die homogene, die heterogene und die enzymatische Katalyse – vergleichend betrachtet. In der 2. Auflage ist ein neues Kapitel zur Stickstofffixierung hinzugekommen. In diesem werden vergleichend die heterogen katalysierte Reaktion, die enzymatisch katalysierte Reaktion (Nitrogenasen) sowie die homogen katalysierte Reaktion gegenübergestellt.

Catalysis, the basic principle for overcoming the kinetic inhibition of chemical reactions, is fundamental in chemistry. In particular, organometallic catalysis plays an overwhelming role in both research and industry. It opens the way to entirely novel synthetic methods and finds widespread applications ranging from mass-production of everyday polymers to stereocontrolled synthesis of bioactive chemicals used as pharmaceuticals and agrochemicals. The targeted development of improved and novel catalysts demands understanding of the relationships between their structures and catalytic properties. Accordingly, this textbook offers the reader a fundamental understanding of the course of organometallic-catalyzed reactions, starting at the molecular level. The initial chapters explain the principles of catalysis and the elementary steps in organometallic catalysis. The book then explores important organometallic-catalyzed reactions, with a focus on mechanism. Current developments are emphasized throughout. Asymmetric synthesis is covered in depth. Finally, the book examines the catalytic behavior of particular metalloenzymes. A look at nitrogen fixation offers a comparative examination of the three major areas of catalysis - homogeneous, heterogeneous, and enzymatic. In addition to problems, the textbook offers solutions, making the book an invaluable learning tool. It is a must-have for advanced students in chemistry and biochemistry, as well as for inorganic and organic chemists, for those working with organometallics, and for those specializing in catalysis.

"Vor ungefahr zwei Jahren trat die Firma Urban & Schwarzenberg mit dem Vorschlage an mich heran, eine Enzyklopadie der technischen Chemie herauszugeben, die ungefahr 10 Bande umfassen und im Verlaufe von 3 - 4 Jahren erscheinen sollte. So wurde denn in fast 2jahriger angestrengter Vorarbeit der Grundplan fur das gesamte Werk entworfen und die Anordnung sowie der Umfang der einzelnen aufzunehmenden Artikel festgestellt. Den Gegenstand des auf breitester Basis angelegten Werkes bilden nicht nur die chemische Grossindustrie und die Metallhuttenkunde mit ihren maschinellen und apparativen Hilfsmitteln, sondern auch die zahlreichen Grenzgebiete, welche sich mit der stofflichen Veranderung oder der Veredelung der Materie uberhaupt befassen. Dem enzyklopadischen Charakter des Werkes entsprechend, musste die Anordnung des Stoffes alphabetisch sein. Doch schien es im Interesse der Ubersichtlichkeit und zur Vermeidung von Wiederholungen zweckmassig, Gebiete, welche stofflich eng zusammen gehoren, auch ausserlich aneinander zu schliessen. Um die Benutzung des Werkes in jeder nur denkbaren Weise zu erleichtern, dienen zur schnelleren Auffindung einer Substanz ausser den zahlreichen Hinweisen die jedem Bande beigegebenen sehr ausfuhrlichen Sachregister; den Schluss soll ein Generalregister bilden, welches die ganze Enzyklopadie umfassen wird. Fur die Rechtschreibung gilt durchweg die wissenschaftliche Schreibweise nach Jansen." [...] Der hier vorliegende achte Band der "Enzyklopadie der technischen Chemie" erlautert von "Natriumverbindungen" bis "Salophen" und ist mit uber 250 historischen Abbildungen illustriert. Dieses Buch ist ein unveranderter Nachdruck der Originalausgabe der zweiten neu bearbeiteten Auflage von 1931."

Metal-arene p-complexes show a rich and varied chemistry. The metal adds a third dimension to the planar aromatic compounds and coordination of a metal to an arene thus not only altering the reactivity of ring-carbons and substituents but also makes possible reactions that lead to chiral non-racemic products. This book, organized in nine chapters and written by leading scientists in the field provides the reader with an up-to-date treatise on the subject organized according to reaction type and use. It covers the wide spectrum of arene activation: from the electrophilic activation of h6-bound areneï⿬ by p-Lewis acid metal complex fragments, to reactions of nucleophilic h2-coordinated arene complexes. The preparation of complexes is detailed, as are the scope, limitations and challenges of reactions in contemporary p-arene metal chemistry with special attention given to asymmetric transformations. The emphasis of the book is on transformations of interest to organic synthesis and on the use of the complexes as catalysts or as chiral ligands. The book is written for academic and industrial researchers in organic, organometallic, and inorganic chemistry as well as for advanced chemistry students

Tin in Organic Synthesis is a systematic presentation of the organic chemistry of tin. This book discusses the significant advances that have been made with regard to the applications of organotin compounds as reagents or intermediates in organic synthesis and points out directions for future developments. This monograph is comprised of 17 chapters divided into four sections. Following a brief introduction to organotin chemistry, the production of the organotin reagents, which are most usually employed in organic synthesis, is described. Special emphasis is placed on the creation of a fresh tin-carbon bond, a preliminary step in numerous fruitful applications. The following chapters are devoted to synthetic applications involving tin-hydrogen, tin-carbon, and tin-heteroatom bonds. The reduction of organic halides, carbonyl compounds, thio, nitrogen compounds, unsaturated carbon-carbon bonds, and seleno and telluro compounds is considered. The discussion then turns to electrophilic cleavages of tin-carbon bonds, which are of possible interest in organic synthesis, along with transmetallation and metallation of organotin compounds. The creation of new carbon-carbon bonds through substitution, addition, or elimination reactions is also examined. The remaining chapters focus on organotin alkoxides, organotin enolates, organotin oxides and peroxides, and organotin esters. This book will be of interest to students and researchers in the field of organic chemistry.

Although the research actIvItIes of dyestuff chemists worldwide have been influenced to a great extent, in recent years, by the need to respond to a variety of environmental issues associated with the manufacture and application of synthetic dyes and pigments, a significant level of targeted research continues to be devoted to new chemistry aimed at enhancing the technical properties of dyes in commerce. This book is a presentation of various aspects of basic research conducted during the past decade but not reported in the recent review literature. The coverage herein is unique in that it emphasizes systematic approaches commonly utilized in the design and synthesis of dyes and pigments and the required intermediates. While it is well known that certain transition metals are important in the synthesis of technically viable metallized dyes for polyamide and protein fibers, these metals are demonstrated in Chapter 1 also to be effective agents in the regiospecific placement of substituents into azo compounds. The scope and limitations of this chemistry are presented. In other synthetic work, a description of the different processes employed to produce the major families of reactive dyes is presented. In Chapter 4, special attention is given to reactive dyes containing more than one reactive group, and to the more recent developments in the field. The two chapters which follow provide a review of the recent literature pertaining to novel chromophores and dyes for the D2T2 process, respectively.

About eight years ago, the catalytic carbonylation of organic nitro compounds was a research field developed enough to justify a rather long review on this subject. Now, we feel that the scientific results and new achievements in this field, very important even from an industrial point of view, require a book in order to be adequately presented. The competition between the catalytic carbonylation of organic nitro compounds and other chemical routes for the synthesis of a variety of organic compounds has not yet come to an end, but many progresses have been done in the former field. We also like to emphasize that this type of research does not only involve relevant industrial problems to be solved, but it opens a research field where the academic interests (mechanism of the reactions, isolation of the intermediates in the catalytic cycles, synthesis of model compounds and so on) can find a lot of opportunities.
