Hydrogenation with Low-Cost Transition Metals describes recent developments in the preparation of catalysts and their catalytic abilities in chemoselective hydrogenation for the production of fine chemicals and pharmaceutical compounds. Emphasizing the use of low-cost metals (Cu, Ni, Fe, and Ag) that are often present in the form of nanoparticles, the book provides valuable reaction mechanism schemes, engineering solutions, and perspective for the field.
The human life is simple as well as quite intrigued and it always tries to find solutions to unending problems and challenges. We know that the need is the mother of invention and the scientists in the world are saints of modern age, as based on their tireless efforts the humans have made a significant progress in various fields as telecommunications, information technology, space technology, infrastructures, food technology through green revolution, life-saving drugs, etc. All these fields need chemicals, which must be manufactured at commercial scales. However, the old technologies are handicapped with unlimited limitations for commercial production of these much needed chemicals. As an ol...
The Fourth Edition of Greene's Protective Groups in Organic Synthesis continues to be an indispensable reference for controlling the reactivity of the most common functional groups during a synthetic sequence. This new edition incorporates the significant developments in the field since publication of the third edition in 1998, including... New protective groups such as the fluorous family and the uniquely removable 2-methoxybenzenesulfonyl group for the protection of amines New techniques for the formation and cleavage of existing protective groups, with examples to illustrate each new technique Expanded coverage of the unexpected side reactions that occur with protective groups New chart covering the selective deprotection of silyl ethers 3,100 new references from the professional literature The content is organized around the functional group to be protected, and ranges from the simplest to the most complex and highly specialized protective groups.
So many compounds, so many experiments reported by so many researchers using so many methods Finding reliable data on bond dissociation energies (BDEs) can be like looking for a needle in a haystack. But these data are crucial to work in chemical kinetics, free radical chemistry, organic thermochemistry, and physical organic chemistry-so where does
The theme of the August 1994 symposium was hydrogel biodegradation and bioapplications. Hydrogels are formed by adding a small amount of cross-linked macromolecular material to a large amount of water, which produces an apparent solid. This volume addresses reversible hydrogels, stimuli-sensitive hydrogels. and some in vivo applications of hydrogels. The volume contains 20 chapters and is directed to organic, physical, polymer, and biochemists as well as biologists, materials scientists, and bioengineers.

With the recent advent of nanotechnology, research and development in the area of nanostructured materials has gained unprecedented prominence. Novel materials with potentially exciting new applications are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured materials join forces to provide ...
Accessible references for researchers and industrialists in this exciting field, covering both developments and applications of catalysis.
Probably more than any other element, iron markedly influences the chemical and physical properties of soils and sediments in the earth. Considering its transition metal status, with potential variation in electronic configuration, ionic radius, and magnetic moment, combined with its abundance and relatively large mass, little wonder that one sees its unique influence on every hand. Pre sentations at the NATO Advanced Study Institute (NATO AS!) on Iron in Soils and Clay Minerals reviewed and discussed the occurrence, behavior, and properties of Fe-bearing minerals found in soils and in the clay mineral groups kaolinite, smectite, and mica. Also discussed at the NATO AS! were the basic chemic...
This book provides state-of-the-art reviews, current research, prospects and challenges of the production of biofuels and chemicals such as furanic biofuels, biodiesel, carboxylic acids, polyols and others from lignocellulosic biomass, furfurals, syngas and γ-valerolactone with bifunctional catalysts, including catalytic, and combined biological and chemical catalysis processes. The bifunctionality of catalytic materials is a concept of not only using multifunctional solid materials as activators, but also design of materials in such a way that the catalytic materials have synergistic characteristics that promote a cascade of transformations with performance beyond that of mixed mono-functional catalysts. This book is a reference designed for researchers, academicians and industrialists in the area of catalysis, energy, chemical engineering and biomass conversion. Readers will find the wealth of information contained in chapters both useful and essential, for assessing the production and application of various biofuels and chemicals by chemical catalysis and biological techniques.
