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.

Immobilization of chiral catalysts is an important tool for improving overall efficiency of catalytic processes. However, heterogeneous catalysts often suffer from decreased activities and supported but still homogeneous catalysts can help overcome this issue. This book covers the most important concepts of homogeneous supported catalysis with an emphasis on enantioselective processes. It describes the state-of-the-art and latest developments in each area whilst critically evaluating the strengths and weaknesses of this important method. The book encompasses ionically-tagged catalysts, supported organocatalysts, supported ionic liquid phases, catalysis using soluble polymers, catalytic dendrimers, fluorous catalysts, water soluble catalysts and non-covalent immobilization methods. Potential developments and ideas for the future are also highlighted. There is a growing demand for effective and recyclable catalysts so this book, covering all the important methods in the field of supported homogeneous catalysis, will appeal to many researchers in academia and industry.

This volume presents the latest developments in the use of organometallic catalysis for the formation of bulk chemicals and the production of energy, via green processes including efficient utilization of waste feedstocks from industry. The chemistry of carbon dioxide relating to its hydrogenation into methanol –an eco-friendly energy storage strategy– and its uses as C1 synthon for the formation of important building-blocks for fine chemicals industry are covered. Catalytic hydrogenations of various functional groups and hydrogen transfer reactions including the use of first row metal catalysts are presented as well as the conversion of alcohols to carboxylates via hydrogen transfer with a zero-waste strategy using water. Transformation of renewable or bio-based raw materials is surveyed through alkene metathesis and C–O bond activations and functionalizations. A green aspect for selective formation of C-C, C-O and C-N bonds involves direct regioselective C–H bond activations and functionalizations. These transformations can now be promoted under mild reaction conditions due to the use photoredox catalyts. C–H bond oxidation using visible light leads mainly to the formation of C–O and C–N bonds, whereas cross-coupled C–C bonds can be formed through the radical additions on (hetero) arenes using photoredox assisted mechanism.

During these early years, the chronic toxicological properties of chemicals were often completely unknown and many unwittingly became indispensable tools of the trade. Early pioneers in green chemistry included Trost (who developed the atom economy principle) and Sheldon (who developed the E-Factor). These measures were introduced to encourage the use of more sustainable chemistry and provide some benchmarking data to encourage scientists to aspire to more benign synthesis. Green chemistry is essentially the design of chemical processes and procedures that reduce or eliminate the use, or the generation, of hazardous substances. Green chemistry is a growing area of research and an increasing number of researchers are now involved in this field. The number of publications has dramatically increased and new recognition of advances made is necessary with respect to other research areas.

The recent explosion of interdisciplinary research has fragmented the knowledge base surrounding renewable polymers. The Chemistry of Bio-based Polymers, 2nd edition brings together, in one volume, the research and work of Professor Johannes Fink, focusing on biopolymers that can be synthesized from renewable polymers. After introducing general aspects of the field, the book's subsequent chapters examine the chemistry of biodegradable polymeric types sorted by their chemical compounds, including the synthesis of low molecular compounds. Various categories of biopolymers are detailed including vinyl-based polymers, acid and lactone polymers, ester and amide polymers, carbohydrate-related polymers and others. Procedures for the preparation of biopolymers and biodegradable nanocomposites are arranged by chemical methods and in vitro biological methods, with discussion of the issue of "plastics from bacteria." The factors influencing the degradation and biodegradation of polymers used in food packaging, exposed to various environments, are detailed at length. The book covers the medical applications of bio-based polymers, concentrating on controlled drug delivery, temporary prostheses, and scaffolds for tissue engineering. Professor Fink also addresses renewable resources for fabricating biofuels and argues for localized biorefineries, as biomass feedstocks are more efficiently handled locally.

This first book to focus on catalytic processes from the viewpoint of green chemistry presents every important aspect: · Numerous catalytic reductions and oxidations methods · Solid-acid and solid-base catalysis · C-C bond formation reactions · Biocatalysis · Asymmetric catalysis · Novel reaction media like e.g. ionic liquids, supercritical CO2 · Renewable raw materials Written by Roger A. Sheldon -- without doubt one of the leaders in the field with much experience in academia and industry -- and his co-workers, the result is a unified whole, an indispensable source for every scientist looking to improve catalytic reactions, whether in the college or company lab.

This book aims to stimulate and promote the wide-ranging aspects of green chemistry and its major role in ensuring sustainable development. The book covers the following areas: green chemistry; green reagents and atom economy; safeguarding the atmosphere; industrial green catalysis; alternative reaction conditions; biocatalysis and green chemistry.
