Book Description
Im Laufe der vergangenen 35 Jahre wurden unzahlige Synthesewege entwickelt, bei denen Ubergangsmetallkomplexe entweder als Reagenzien oder als Katalysatoren fungieren. Dieses Buch bietet besonders denjenigen Synthesechemikern interessante und moderne Einblicke, die bisher noch nicht mit den vielfaltigen Moglichkeiten der Organometallchemie mit Ubergangsmetallen vertraut sind. Zu wichtigen ubergangsmetallkatalysierten Reaktionen werden Anwendungsbeispiele diskutiert. (01/00)

Book Description
An expert overview of current research, applications, and economic and environmental advantages The study and development of new homogeneous catalysts based on first-row metals (Mn, Fe, Co, Ni, and Cu) has grown significantly due to the economic and environmental advantages that non-noble metals present. Base metals offer reduced cost, greater supply, and lower toxicity levels than noble metals?enabling greater opportunity for scientific investigation and increased development of practical applications. Non-Noble Metal Catalysis provides an authoritative survey of the field, from fundamental concepts and computational methods to industrial applications and reaction classes. Recognized experts in organometallic chemistry and homogeneous catalysis, the authors present a comprehensive overview of the conceptual and practical aspects of non-noble metal catalysts. Examination of topics including non-innocent ligands, proton-coupled electron transfer, and multi-nuclear complexes provide essential background information, while areas such as kinetic lability and lifetimes of intermediates reflect current research and shifting trends in the field. This timely book demonstrates the efficacy of base metal catalysts in the pharmaceutical, fine-chemical, and agrochemical industries, addressing both environmental and economic concerns. Providing essential conceptual and practical exploration, this valuable resource: -Illustrates how unravelling new reactivity patterns can lead to new catalysts and new applications -Highlights the multiple advantages of using non-noble metals in homogenous catalysis -Demonstrates how the availability of non-noble metal catalysis reduces costs and leads to immense savings for the chemical industry -Reveals how non-noble metal catalysis are more sustainable than noble metals such as palladium or platinum Non-Noble Metal Catalysis: Molecular Approaches and Reactions is an indispensable source of up-to-date information for catalytic chemists, organic chemists, industrial chemists, organometallic chemists, and those seeking to broaden their knowledge of catalytic chemistry.

Book Description
"Transition metal catalysis has revolutionized modern synthetic methodology by enabling the facile activation and generation of sp2 and sp3 (hetero)carbon bonds. Thus, organometallic complexes are ubiquitous in the production of commodity chemicals, synthetic building blocks, and polymers. Although transition metal catalysis has been broadly used, there is still room for improvement in its efficiency, sustainability, and applicability. To this extent this dissertation will focus on employing different strategies to address these challenges. Chapter 2 will discuss the implementation of an electrocatalytic system for the metal catalyzed oxidation of alcohols and amines using benzoquinones as regenerable hydrogen acceptors. Chapter 3 will illustrate the design and development of a novel bisoxazoline-pincer ligated cobalt complex and its catalytic ability to hydrogenate alkenes, followed by discussion of exploratory work of this scaffold's early transition metal analogs and potential further catalytic reactivity. Lastly, chapter 4 will examine a set of trispyrazoylborate metal complexes for their capacity to perform direct arene borylation and compare the resulting reactivity to their heavily studied isoelectronic cyclopentamethyldienyl iridium counterparts. Analysis of the reaction reveals formation of nanoparticles leading to further characterization via XRD and TEM imaging."--Page x.

Book Description
Transition metal catalysis belongs to the most important chemical research areas because a ubiquitous number of chemical reactions are catalyzed by transition metal compounds. Many efforts are being made by industry and academia to find new and more efficient catalysts for chemical processes. Transition metals play a prominent role in catalytic research because they have been proven to show an enormous diversity in lowering the activation barrier for chemical reactions. For many years, the search for new catalysts was carried out by trial and error, which was costly and time consuming. The understanding of the mechanism of the catalytic process is often not very advanced because it is difficult to study the elementary steps of the catalysis with experimental techniques. The development of modern quantum chemical methods for calculating possible intermediates and transition states was a breakthrough in gaining an understanding of the reaction pathways of transition metal catalyzed reactions. This volume, organized into eight chapters written by leading scientists in the field, illustrates the progress made during the last decade. The reader will obtain a deep insight into the present state of quantum chemical research in transition metal catalysis.

Book Description
This thesis describes the development of novel methodologies for transition metal catalyzed syntheses of industrially relevant substances. Herein, the efficiency of innovative catalysts for hydrogen autotransfer conversions which enable molecular transformations displaying advantages over classical routes is investigated. Moreover, the thesis presents new materials for the amidocarbonylation. Finally, a new procedure for the selective synthesis of Z-alkenes via twofold utilization of palladium atoms - initially as homogeneous and subsequently as heterogeneous catalyst - is presented.eng

Book Description
This book concentrates on industrially relevant reactions which are catalyzed by heterogeneous and homogeneous catalysts. Homogeneous catalysis by metal complexes is treated jointly with heterogeneous catalysis using metallic and non-metallic solids. In both areas the high degree of sophistication of spectroscopic techniques and theoretical modelling has led to an enormous increase in our understanding at the molecular level. This holds for the kinetics of the reactions and the reactivities of the catalysts, as well as for the syntheses of the catalytic materials. The development of catalysis science since the first edition of this book has necessitated a thorough revision, including special chapters on biocatalysis, catalyst characterization and adsorption methods. The multidisciplinary nature of catalysis is reflected in the choice of a novel combination of basic disciplines which will be refreshing and inspiring to readers.

Book Description
Homogeneous catalysis is an important strategy for the synthesis of high-valued chemicals. L. Brandsma has carefully selected and checked the experimental procedures illustrating the catalytic use of copper, nickel, and palladium compounds in organic synthesis. All procedures are on a preparative scale, make economic use of solvents and catalysts, avoid toxic substances and have high yields.
