Optimize Your Chemical Database

Design and Use of Relational Databases in Chemistry helps programmers and users improve their ability to search and manipulate chemical structures and information, especially when using chemical database "cartridges." It illustrates how the organizational, data integrity, and extensibility properties of relational databases are best utilized when working with chemical information.

The author facilitates an understanding of existing relational database schemas and shows how to design new schemas...

Palladium is a remarkable metal. In particular, organopalladium chemistry has made remarkable progress over the last 30 years. That progress is still continuing, without any end in sight. This book presents a number of accounts and reviews on the novel Pd-catalyzed reactions discovered mainly in the last five years. The book covers Pd-catalyzed reactions that are new entirely different from the more standard ones. Topics such as new reactions involving ss-carbon elimination and formation of palladacycles as key reactions, cross-coupling of unactivated alkyl electrophiles with...

It was only in the early 1990s that carbenes with the carbene carbon being incorporated in a nitrogen containing heterocycle (N-heterocyclic carbenes or NHCs) were found to be stable enough to be isolated. Since the first report on the application of NHCs as ligands in transition metal catalysis in 1995, NHC have found numerous applications and have been established as a versatile and indispensable class of ligands. For many reactions like metathesis or cross-coupling reactions NHCs have often become the ligands of choice, allowing otherwise difficult transformations. In this book leading...

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....

Organ regeneration, once unknown in adult mammals, is at the threshold of maturity as a clinical method for restoration of organ function in humans. Several laboratories around the world are engaged in the development of new tools such as stem cells and biologically active scaffolds. Others are taking fresh looks at well-known clinical problems of replacement of a large variety of organs: Bone, skin, the spinal cord, peripheral nerves, articular cartilage, the conjunctiva, heart valves and urologic organs. Still other investigators are working out the mechanistic pathways of regeneration...

This series presents critical reviews of the present position and future trends in modern chemical research.

Molecular ruthenium catalysts, during the last decade, have provided new indispensable synthetic methods that cannot be promoted by other catalysts, and they now constitute an emerging field for the selective preparation of fine chemicals. The major reaction types for carbon-carbon and carbon-heteroatom bond formation, most of them with atom economy, are comprehensively discussed by leading experts. The authors highlight the most important discoveries in ruthenium catalysis and propose activation processes, some of them being still controversial. They illustrate the innovation and...

Multiphase catalysis in recent years has been shown in academia and industry to be the emerging key technology for the competitive and sustainable production of fine chemicals in the next decades. It convincingly unites the indispensable core advantages of homogeneous catalysis with future governmental and industrial sustainability criteria. In a joint effort by seven of Germany's most distinguished scientists in the field and four renowned industry partners a research consortium was established which for the first time has systematically explored and related the main issues and mutual...
