Heterocyclic chemistry constitutes the largest branch of chemistry, covering almost two-thirds of literature in the field. In addition, around 90% of naturally-occurring molecules have heterocycles as their core structure. Therefore, as a central part of organic chemistry, the discovery of new methodologies in synthesizing heterocyclic compounds is essential to their continued application and development. Transition metal catalysts offer a low cost and often low toxicity pathway for heterocycles synthesis, while the use of noble metals represents an alternative form of experimentation which is discussed in the book. Noble Metals, Noble Value provides the first comprehensive analysis of the applications of the noble metals of ruthenium (Ru), rhodium (Rh) and palladium (Pd) catalysts in heterocycles synthesis. Pairs of chapters are dedicated to summarizing each of the metals when applied to either five- or six-membered heterocyclic syntheses. An introduction to the importance of heterocycles and possible procedures for the preparation of heterocyclic compounds is also given. With up to date research and findings, this review is excellently suited to academics and professionals in the field of chemistry, with a particular focus on the specialities of biological, catalytic and organic chemistry.

The demand for hydroprocessing catalysts has shown an increasing trend, because of their applications in refining of petroleum and biofuels, in order to comply with strict environmental regulations controlling emissions from transportation vehicles. Transport fuel is dominated by fossil fuels with carbon emission intensive production methods. If we are to move away from these sources, the alternative is to produce liquid fuels from agricultural stocks -- crops, crop waste, forestry waste or algae. Converting these feedstocks into high quality fuels is a considerable challenge. By describing the current status in processing agricultural feedstock into high quality liquid transport fuels, the authors set out the means to develop better chemistry and catalysis for the necessary conversion processes. This book offers an intriguing insight into the mechanisms and protocols involved in new hydroprocessing catalysts and processes, and covers the methods for upgrading these liquids to modern transport vehicles suitable for operation in modern gasoline and diesel engines. It provides an introduction to the mechanism of hydroprocessing reactions, application of different metals in hydroprocessing, the effect of catalyst supports, applications in refining new feedstock, renewable fuels standards, the management of spent hydroprocessing catalysts, and hydrogen production. Hydroprocessing Catalysts and Processes will prove useful for both researchers in academe and industry concerned with future fuels development and treatment to produce current and future liquid transport fuels.

Die homogene Übergangsmetallkatalyse ist noch eine noch junge Wissenschaft, hat aber bereits zahlreiche großindustrielle Anwendungen gefunden. Langkettige Olefine, Essigsäure, Adipodinitril und Aldehyde werden heute überwiegend homogen-katalytisch hergestellt. Die Stärke der homogenen Katalyse liegt aber insbesondere bei der Synthese von Pharma- und Feinchemikalien, wo wenige Syntheseschritte eine lange Anfolge von Stufenreaktionen überflüssig machen. Dieses Buch gibt einen kompakten Überblick über die Prinzipien und Reaktionsmöglichkeiten der Homogenkatalyse, verdeutlicht an ausgesuchten Einzelbeispielen. Studierende, Chemiker und Ingenieure können dieses Buch zum ausführlichen Studium oder als Nachschlagewerk nutzen.
