Book Description
This book presents recent advances in and perspectives on the use of organoselenium compounds, primarily highlighting the new frontiers in the field of Green Chemistry, their therapeutic and biological relevance and new materials. Throughout its 200 pages, readers will find an updated and comprehensive review of new aspects of organoselenium chemistry and biochemistry. Fully referenced and written in an easy to read style, it offers readers a primary resource for including organoselenium derivatives in their projects. This book will be of interest to specialists, students and researchers involved in a broad range of fields, from synthetic green chemistry to medicinal chemistry and the chemistry of natural products. The connection between organoselenium compounds and green chemistry, despite having only recently emerged, is one of the subjects of this book. The first chapter highlights the use of Se-containing molecules as reagents and catalysts in new green protocols to access important organic transformations. The book provides a wealth of examples of bioactive Se-containing molecules, especially focusing on those with potential therapeutic uses. The second chapter focuses on the state of the art concerning the role of organoselenium compounds as antioxidants, GPx mimics, and derivatives endowed with different bioactive properties. “Organoselenium in nature” is the title of the third chapter, which equips readers with essential information on the main natural organoselenium compounds and where they are found. Selected aspects of the metabolism of selenium in plants and microorganisms are also discussed. In closing, the book includes a chapter dedicated to recent advances concerning the nonbonding interactions between organochalcogen compounds. This is currently a hot topic in selenium chemistry and biochemistry, and here readers will find key insights into the chalcogen bond and its role in the biological activity of organoselenium compounds.

Book Description
Organochalcogen compounds reviews the state of the art in new green protocols involving organochalcogen compounds (Se, S, and Te), including the use of nonconventional reaction media, alternative solvents, and solvent-free protocols to prepare these important compounds. Bringing together several leading researchers in organochalcogen chemistry, it provides an authoritative overview of the current state of the field and compiles recent advances in methodologies for the application of green chemistry principles in compound development. These include the use of organochalcogen compounds as intermediates, catalysts, or target products across a range of applications. The recent developments outlined in in the book reflect the efforts of the researchers in this area to move toward a more sustainable chemistry, giving the book the dual benefit of highlighting the latest developments in the field while also showing how the principles of green chemistry can effectively be included in active research projects. Thus it is a valuable reference for chemists, particularly those working in organic, green, and synthetic chemistry across both academia and industry. Highlights green synthetic methods with potential application in the synthesis of natural compounds or other biologically active scaffolds Explores the chemical modification of natural compounds by insertion of organochalcogen groups for the preparation of boosted bioactive semisynthetic molecules Discuss how redox catalysis and catalysis in flow conditions using eco-friendly oxidant can provide new opportunities for the synthesis of linear ad cyclic derivatives

Book Description
Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973

Book Description
The chemistry of heterocyclic compounds now forms one of the most extensive and important branches of organic chemistry. The rapid expansion of investigation in this field is due largely to the ever increasing practical importance of heterocyclic com pounds. The present stage in the development of organic chemistry and closely allied branches of biology is characterized by extensive investigation of physiologically active substances encountered in the plant and animal world and playing important parts in the life processes of micro- and macro-organisms. This extensive inves tigation of alkaloids, vitamins, hormones, antibiotics and their synthetic substitutes, and also of substances that control the bio chemical processes of the nervous system, has acted as a powerful stimulus to the further development of the chemistry of hetero cyclic compounds. Moreover, there are many well known applications of heterocyclic compounds in the manufacture of dyes, synthetic resins, synthetic rubbers, and other important materials. In response to growing demands, several monographs and treatises on the chemistry of heterocyclic compounds have appeared in recent years, the most comprehensive of these being the series "Heterocyclic Compounds," edited by R. C. Elderfield, which is already appearing in Russian translation. On the other hand, the lack of a practical guide to the laboratory preparation of hetero cyclic compounds is being felt more and more.

Book Description
Nature endows us with a treasure chest of Green Gold full of amazing ‘redox-active’ substances which interfere with numerous biological processes in our own body, in animals, bacteria, fungi and plants. Whilst such natural products are all around and also in us, we still do not fully understand how these compounds actually work. This book attempts to resolve some of the mysteries and riddles associated with such products. Written by more than thirty international experts from academia and industry, it places a focus on modern developments in this field and considers such natural products from various angles, from their isolation and characterization all along to product development and commercialization. Throughout, the reader will be confronted with modern approaches which enable the efficient identification and isolation of new natural products, help to elucidate their mode(s) of action and permit practical uses in Medicine, Cosmetics, Agriculture, Industry and as functional foods.
