The systematic approach will provide undergraduate readers with a concise overview of this area of inorganic chemistry.

The interaction of transition metals with unsaturated molecules has led to fundamental insights in the nature of the chemical bond which, in turn, has provided the basis of important present-day applications such as transition metal mediated synthesis or homogeneous and heterogeneous catalysis. This slim volume outlines the chemistry and discusses the bonding in of some of the most important classes of organometallic compounds: the complexes of transition metals with Pi-ligands such as alkenes, alkynes, arenes, and cyclopentadienyl and allyl ligands. The material covered follows on from Organometallics I which covers the chemistry of complexes with metal-carbon delta-bonds. Synthetic and reactivity aspects of each class of compounds are illustrated with pertinent examples from the recent chemical literature. Highlighted excursions relate the fundamental chemistry to current synthetic or catalytic applications.

This straightforward introduction looks at the properties and reactions of main group organometallic compounds, placing particular emphasis on their applications in synthesis. Written in a simple, readable style, the book adopts a logical approach to this important area of organic chemistry, and provides the student with a clear account of all aspects of the field. Study problems are included at chapter ends, along with many suggestions for further reading.

An outstanding international scientific event in the field of metathesis chemistry, the NATO ASI "Green Metathesis Chemistry: Great Challenges in Synthesis, Catalysis and Nanotechnology" has been recently organized in Bucharest, Romania (July 21- August 2, 2008). Numerous renowned scientists, young researchers and students, convened for two weeks to present and debate on the newest trends in alkene metathesis and identify future perspectives in this fascinating area of organic, organometallic, catalysis and polymer chemistry with foreseen important applications in materials science and technology. Following the fruitful practice of NATO Advanced Study Institutes, selected contributions covering plenary lectures, short communications and posters have been compiled in this special volume dedicated to this successful convention on green metathesis chemistry.

General interest was primarily focused on relevant "green chemistry" features related to all types of metathesis reactions (RCM, CM, enyne metathesis, ADMET and ROMP). Diverse opportunities for green and sustainable technologies and industrial procedures based on metahesis have been identified. Largely exemplified was the utility of this broadly applicable strategy in organic synthesis, for accessing natural products and pharmaceuticals, and also its ability to fit in the manufacture of smart and nanostructured materials, self-assemblies with nanoscale morphologies, macromolecular engineering.

Organometallics playa key role in organic synthesis. Carbon carbon bond formation without main group and transition metal based reagents as well as catalysts is hardly imaginable, and the tremendous success in recent years in the field of stereoselective synthesis of complex biologically active com pounds would have been impossible without the advances in organometallic chemistry. From the wealth of carbon carbon bond forming reactions in organotransition metal chemistry many new methods have evolved. This was aided considerably by a deepening of our understanding of the relevant reaction mechanisms. Organometallic chemistry is the bridge par excellence between the traditional fields of inorganic and organiC chemistry. It was the intention of the "Volkswagen-Stiftung" to broaden this bridge by starting in 1986 the new interdisciplinary program "Organic Synthesis via Organo metallics." From its very beginning this program grew up after 6 years to now more than 60 projects and its encompasses besides its main topic "Organic Synthesis" mechanistic and structural aspects of organometallic chemistry as well. In a series of symposia sponsored by the "Volkswagen-Stiftung," the former of which were held in Hamburg (February 1986), Wiirzburg (October 1988) and Marburg (July 1990), a forum for intensive discussions and SCientific exchange was established. There, scientists participating in the program met with other experts form academia and from industry. The forth symposium was held in Aachen from July 15 to 18, 1992."

A series of critical reviews and perspectives focussing on specific aspects of organometallic chemistry interfacing with other fields of study are provided. For this volume, the critical reviews cover topics such as the activation of "inert" carbon-hydrogen bonds, ligand design and organometallic radical species. For example, Charlie O'Hara discusses how mixed-metal compounds may perform the highly selective activation of C-H bonds and, in particular, how synergic relationships between various metals are crucial to this approach. The chemistry of a remarkable series of air-stable chiral primary phosphine ligands is discussed in some depth by Rachel Hiney, Arne Ficks, Helge M(3)ller-Bunz, Declan Gilheany and Lee Higham. This article focuses on the preparation of these ligands and also how they may be applied in various catalytic applications. Bas De Bruin reports on how ligand radical reactivity can be employed in synthetic organometallic chemistry and catalysis to achieve selectivity in radical-type transformations. As well as highlighting ligand-centered radical transformations in open-shell transition metals, an overview of the catalytic mechanism of Co(II)-catalysed olefin cyclopropanation is given, showing that enzyme-like cooperative metal-ligand-radical reactivity is no longer limited to real enzymes. Valuable and informative comprehensive reviews in the field of organometallic chemistry are also covered in this volume. For example, organolithium and organocuprate chemistry are reviewed by Joanna Haywood and Andrew Wheatley; aspects in Group 2 (Be-Ba) and Group 12 (Zn-Hg) compounds by Robert Less, Rebecca Melen and Dominic Wright; metal clusters by Mark Humphrey and Marie Cifuentes; and recent developments in the chemistry of the elements of Group 14 - focusing on low-coordination number compounds by Richard Layfield. This volume therefore covers many synthetic and applied aspects of modern organometallic chemistry which ought to be of interest to inorganic, organic and applied catalysis fields.

Providing an invaluable resource, this volume contains analysed, evaluated and distilled information on the latest in organometallic and coordination chemistry research and emerging fields. With continued increases in the variety of information available, researchers can find it difficult to keep up to date with the literature in their field. The reviews in this volume range in scope and include recent developments in homogeneous catalysis for the functionalization of carbon dioxide, early transition metal complexes and their uses in medicinal chemistry, homogeneous gold catalysis under microwave irradiation: a greener approach and properties of metal complexes of mesoionic carbenes. This volume is a key reference for researchers in academic and industrial settings.

This book describes the development of two kinds of continuous-flow transformation using heterogeneous catalysts, and explains how they can be applied in the multistep synthesis of active pharmaceutical ingredients. It demonstrates and proves that fine chemicals can be synthesized under continuous-flow conditions using heterogeneous catalysis alone. Importantly, the book also proposes a general concept and strategy for achieving multistep flow synthesis and developing heterogeneous catalysts, and shows that commercially available anion exchange resin can be used as a water-tolerant strong base catalyst for various types of continuous-flow aldol-type reaction. Reviewing the state of the art in heterogeneous catalysis in flow chemistry - a "hot topic" and rapidly developing area of organic synthesis - the book will provide readers with a deeper understanding of fine chemical flow synthesis and its future prospects.

This new and important book presents recent advances in organometallic chemistry which is based on the reactions and use of a class of compounds (R-M) that contain a covalent bond between carbon and metal. They are prepared either by direct reaction of the metal with an organic compound or by replacement of a metal from another organometallic substance. Research in organometallic chemistry is also conducted in the areas of cluster synthesis, main-group derivatives in unusual oxidation states, organometallic polymers, unstable organometallic compounds and intermediates in matrices, structure determination of organometallic compounds in the solid state [X-ray diffraction] and gaseous states [electron diffraction], and mechanisms of reactions of transient silylenes and related species. In addition to the traditional metals and semimetals, elements such as selenium, lithium and magnesium are considered to form organometallic compounds, e.g. organomagnesium compounds MeMgI, iodo(methyl)magnesium and diethylmagnesium which are Grignard reagents an organo-lithium compound BuLi butyllithium; Organometallic compounds often find practical use as catalysts, the processing of petroleum products and the production of organic polymers.

A black hole is a point of extreme mass in space-time with a radius, or event horizon, inside of which all electromagnetic radiation (including light) is trapped by gravity. A black hole is an extremely compact object, collapsed by gravity which has overcome electric and nuclear forces. It is believed that stars appreciably larger than the Sun, once they have exhausted all their nuclear fuel, collapse to form black holes: they are "black" because no light escapes their intense gravity. Material attracted to a black hole, though, gains enormous energy and can radiate part of it before being swallowed up. Some astronomers believe that enormously massive black holes exist in the centre of our galaxy and of other galaxies. This book brings together leading research from throughout the world.
