The last 15 years have witnessed significant developments in the efficiency and scope of the application of DKR. These now offer a serious alternative to conventional methods for asymmetric synthesis. Indeed, impressive examples using new enzymes and major progress in the DKR of racemates have taken place over the past few years. The powerful combination of enzymes and metals has also been the subject of spectacular development. In addition, a new type of DKR, involving organocatalysts, has recently appeared. Although asymmetric catalysis has undergone development during the last two decades, the most common industrial process used to obtain enantiomerically pure compounds is still via resol...
There are a lot of books available about the chemistry and biology of sulfur. However, this is the first book with a compilation of all relevant Sulfur containing reagents. Synthetic chemists, most particularly in the medicinal and pharmaceutical chemists, are often called upon to prepare compounds that contain Sulfur as a key structural feature. In the past, this seemed to be a domain for specialists; today every synthetic chemist working in these area is expected to synthesize compounds containing sulfides, sulfates, sulfones, etc. This book offers an important source of information for the selection and handling of the right reagents.
This volume constitutes the thoroughly refereed post-conference proceedings of the 7th International Conference on Mathematical Methods for Curves and Surfaces, MMCS 2008, held in Tønsberg, Norway, in June/July 2008. The 28 revised full papers presented were carefully reviewed and selected from 129 talks presented at the conference. The topics addressed by the papers range from mathematical analysis of various methods to practical implementation on modern graphics processing units.
Kohlenstoff und Wasserstoff - jedem Chemiestudenten sind sie wohlbekannt als Grundbausteine der Organischen Chemie. Welch ungeahnte Vielfalt von Verbindungen sich aus diesen Elementen aufbauen läßt, zeigt dieses einzigartige Buch. Dabei beschränkt es sich nicht nur auf die bloße Darstellung von Struktur und Eigenschaften von Kohlenwasserstoffen, sondern verdeutlicht überdies die Herausforderung, die Moleküle wie Tetrahedran, Superphan oder Dodecahedran an das synthetische Geschick eines jeden Organikers stellen. In seinem Konzept folgt das Werk - retrosynthetische Analyse der Reaktionssequenzen, ausführliche Erläuterung der Synthesemethoden, umfassende Verweise auf die Originalliteratur - dem Bestseller von K. C. Nicolaou und E. J. Sorensen "Classics in Total Synthesis". Es vermittelt so eine Fülle von generellen Prinzipien und Methoden der organischen Synthese und empfiehlt sich auf Jahre hinaus als Standardwerk, das jedem Studenten und Organiker in Forschung und Lehre geläufig sein sollte.
Shell structures and their components are applied in many engineering fields. Designers are attaching ever increasing importance to nonlinear responses such as large deformations, instabilities and nonlinear material properties in their design analysis. This volume presents a careful selection of papers from the ICES '88 Conference covering various aspects of nonlinear shell responses.
III-V semiconductors have attracted considerable attention due to their applications in the fabrication of electronic and optoelectronic devices as light emitting diodes and solar cells. The electrical properties of these semiconductors can also be tuned by adding impurity atoms. Because of their wide application in various devices, the search for new semiconductor materials and the improvement of existing materials is an important field of study. Doping with impurities is a common method of modifying and diversifying the properties of physical and chemical semiconductors. This book covers all known information about phase relations in quaternary systems based on III-V semiconductors, provid...
The aim of this book is to help people performing routine operations in Organic Synthesis in a laboratory. This book, the first one in a series, focuses on the oxidation of alcohols to aldehydes and ketones. Probably, this is the most important routine operation in Organic Synthesis.
This edited volume presents innovative current research in the field of Science Education. The chapter’s deal with a wide variety of topics and research approaches, conducted in a range of contexts and settings. Together they make a strong contribution to knowledge on science teaching and learning. The book consists of selected presentations from the 12th European Science Education Research Association (ESERA) Conference, held in Dublin, Ireland from 21st to 25th August, 2017. The ESERA community is made up of professionals with diverse disciplinary backgrounds from natural sciences to social sciences. This diversity enables a rich understanding of cognitive and affective aspects of scienc...
