9-Borabicyclo 3.3.1]nonane, a commercially available reagent, is the most versatile hydroborating reagent to synthesize organoboranes (B-R-9-BBN). The reagent exhibits remarkable regio-, chemo-, and stereoselectivity during hydroboration reactions. The organoboranes can be converted to C-H, C-O, C-N, C-S, C-halogen, C-metal and above all C-C bonds. In addition, the suitable substituted / unsaturated R of B-R-9-BBN can be utilized to produce dienes, enynes, allenes etc. with defined stereochemistry. 9-BBN s derivatives have been elegantly used for the asymmetric reduction of ketone moiety....

This volume contains selected papers presented at the 42nd Biennial Meeting of the Kolloid-Gesellschaft held at the RWTH Aachen University September 26-28, 2005. The contributions in this volume represent the diversity of research topics in colloid and polymer science. They include the investigation of synthesis and properties of advanced temperature sensitive particles and their biomedical applications, drug delivery systems, foams, capsules, vesicles and gels, polyelectrolytes, nanoparticles surfactants and hybrid materials.

Eighty per cent of all compounds produced in the chemical and pharmaceutical industries require at least one essential catalytic step during their synthesis. At the same time the use of hydrocarbons as a feed-stock for commodity and fine chemicals typically requires an oxidation step, which is usually mediated by a transition metal compound. Consequently oxidation catalysis is a major research field in chemistry, both in academia and in industry. In many such processes, species with metal-carbon bonds are formed as key intermediates, and these processes represent the primary focus of this...

The last 10 years have seen a seismic shift in therapeutic product development and testing. In both the pharmaceutical (both small and large molecule) and medical device sectors, the vast majority of testing and evaluation of products is not performed within innovator companies, but rather has been outsourced to a growing universe of commercial organizations. The authors both have more than 30 years experience in this field, and both have worked within innovator companies, for CROs, and as consultants in the field. "Contract Research and Development Organizations: Their Role in Global...

The use of phosphine derivatives has historically induced the tremendous development of catalysis (both non-asymmetric and asymmetric). Although the chemistry of amines is more documented, the use of nitrogen-containing ligands only appeared recently. Nevertheless, during the last ten years, the results describing chiral diamine preparations and their uses in asymmetric catalysis and synthesis are increasing faster than their phosphorus counterparts. The reader will find in this volume the most recent methods for the synthesis of chiral diamines as well as their applications in asymmetric...

This book provides an excellent overview on state-of-the-art of modern organocatalysis. It presents the contributions from leading experts, with backgrounds in academia and industry, to an Ernst Schering Research Foundation Symposium held in April 2007. It will be of interest to those who want a general overview of the topic, but also to those who want to learn more about the state-of-the-art, current trends and perspectives in this highly dynamic field of research.

This series presents critical reviews of the present position and future trends in modern chemical research. It contains short and concise reports on chemistry, each written by the world renowned experts. The series is still valid and useful after five or ten years.
