"Palladium-Catalyzed Modification of Nucleosides, Nucleotides and Oligonucleotides describes the procedures and protocols related to the modification of nucleosides, nucleotides and oligonucleotides via Pd-mediated cross-coupling processes. The book highlights the growing area of nucleic acid modification and how Pd-mediated coupling reactions can assist this development. Users will find key synthetic protocols for these reactions in this latest volume in the Latest Trends in Palladium Chemistry series. As most of the research in the field of antiviral agents has centered on the use of modified nucleosides that have exhibited promising activity, this book provides an up-to-date reference for both professionals in industry and other interested parties" -- elsevier.com.

This comprehensive handbook will be an indispensable research tool for chemists. Handbook of Palladium Catalysed Organic Reactions provides a synoptic description of the main types of reactions which are catalyzed by Palladium and the mechanism which causes these reactions. Each reaction is presented in graphical form and classified according to the type of transformation involved.Other books covering the use of Palladium complexes as catalysts have been written, but the Handbook is the only to offer a synoptic view, showing the catalytic cycle of each reaction.

The author has developed novel methodologies for highly efficient construction of functionalized heterocycles by palladium-catalyzed domino/cascade cyclization of allenes and related compounds containing appropriate nucleophilic group(s). Based on these methodologies, enantioselective total syntheses of bioactive natural products, pachastrissamine (26% overall yield in seven steps), lysergic acid (4.0% overall yield in fifteen steps), lysergol (3.6% overall yield in fifteen steps) and isolysergol (8.2% overall yield in eleven steps) have been achieved. These are more facile synthetic route than those previously reported. These findings would contribute to the development of efficient synthetic methods for biologically active compounds containing a complex structure.

Find out how theoretical calculations are used to determine, elucidate and propose mechanisms for Pd-catalyzed C-C cross-coupling reactions in Max Garcia Melchor's outstanding thesis. Garcia Melchor investigates one of the most significant and useful types of reactions in modern organic synthesis; the Pd-cross coupling reaction. Due to its versatility, broad scope and selectivity under mild conditions, this type of reaction can now be applied in fields as diverse as the agrochemical and pharmaceutical industry. Garcia Melchor studies the reaction intermediates and transition states involved in the Negishi, the copper-free Sonogashira and the asymmetric version of Suzuki-Miyaura coupling. He also characterizes and provides a detailed picture of the associated reaction mechanisms. The author has won numerous prizes for this work which has led to over eight publications in internationally renowned journals.

The future of the precious metals is shiny and resistant. Although expensive and potentially replaceable by transition metal catalysts, precious metal implementation in research and industry shows potential. These metals catalyze oxidation and hydrogenation due to their dissociative behavior toward hydrogen and oxygen, dehydrogenation, isomerization, and aromatization, etc. The precious metal catalysts, especially platinum-based catalysts, are involved in a variety of industrial processes. Examples include Pt–Rh gauze for nitric acid production, the Pt/Al2O3 catalyst for cyclohexane and propylene production, and Pd/Al2O3 catalysts for petrochemical hydropurification reactions, etc. A quick search of the number of published articles in the last five years containing a combination of corresponding “metals” (Pt, Pd, Ru, Rh and Au) and “catalysts” as keywords indicates the importance of the Pt catalysts, but also the continuous increase in the contribution of Pd and Au. This Special Issue reveals the importance of precious metals in catalysis and focuses on mono- and bi-metallic formulations of any supported precious metals and their promotional catalytic effect of other transition metals. The application of precious metals in diverse reactions, either homogeneous or heterogeneous, and studies of the preparation, characterization, and applications of the supported precious metal catalysts, are presented.

Adequate quality of life and well-being of modern societies is only achievable with sustainable manufacturing processes that efficiently use raw materials, eliminate waste, and avoid the use of hazardous materials. All this is hardly conceivable without catalysis. In a world concerned with the exploitation of natural resources, catalysis can offer direct synthesis routes that maximize resource efficiency. The Iberoamerican society is far too significant and far too involved in global development, owing to its natural richness of resources, not to have an essential role in current developments and future directions. Catalysis, in the Iberoamerican academic and industrial communities, is recognized as a relevant scientific discipline that supports several strategic industrial sectors through the manufacturing of products and materials, and the operationalization of processes to produce energy and other utilities. As a reflection of this, once every two years the Iberoamerican Congress on Catalysis takes place to share and discuss the state-of-the-art of this discipline with the Federation of Iberoamerican Catalysis Societies. This book collected sixteen outstanding contributions, stemming from this exceptional event—one which will undoubtedly mark a turning point and could be a source of inspiration to all those involved in catalysis, particularly the young generation of competent researchers taking their first steps in this incredibly complex and beautiful discipline.
