A timely and authoritative treatise on the chemistry and diverse applications of chalcogenadiazoles - the five-membered rings containing two carbons, two nitrogens, and one chalcogen (an member of group 16, the oxygen family). The number of different chalcogenadiazoles and their structural diversity make it difficult to gain a clear understanding of the subject by studying an individual system in isolation. Chalcogenadiazoles: Chemistry and Applications emphasizes general features of this class of heterocyclic compounds. It concentrates on properties of each class of chalcogenadiazoles and their cycle-fused derivatives, considering chemical reactions of functional groups only in cases when these reactions permit to characterize the heterocycles as substituents or in respect of its aromaticity.Covering an important and rapidly developing branch of heterocyclic chemistry, this book is an essential resource for students, young professionals and experienced specialists in adjacent fields who are interested in: Trends in the search for compounds with established bioactivity or use in medicine, as agrochemicals, or as reagents for environmental and biochemical analysis Differences in classes of chalcogenadiazoles with respect to their degree of aromaticity and similar general concepts helpful to the nonspecialist The effects of the chalcogen nature and the alternation manner of all atomic constituents on properties of these heterocyclic compounds Combining data from organic, biological, medicinal, materials science, and supramolecular chemistry, Chalcogenadiazoles: Chemistry and Applications is an important source of information not only for chemists in the fields of organic, inorganic, and organometallic chemistry, but also for anyone interested in the research and development of chalcogenadiazoles and related species.

Consolidating knowledge from a number of disciplines, Ion-Radical Organic Chemistry: Principles and Applications, Second Edition presents the recent changes that have occurred in the field since the publication of the first edition in 2003. This volume examines the formation, transformation, and application of ion-radicals in typical conditions of organic synthesis. Avoiding complex mathematics, the author explains the principles of ion-radical organic chemistry and presents an overview of organic ion-radical reactions. He reviews methods of determining ion-radical mechanisms and controlling ion-radical reactions. Wherever applicable, the text addresses issues relating to ecology and biomedical concerns as well as inorganic participants of the ion-radical organic reactions. After reviewing the nature of organic ion-radicals and their ground-state electronic structure, the book discusses their formation, the relationship between electronic structure and reactivity, mechanism and regulation of reactions, stereochemical aspects, synthetic opportunities, and practical applications. Additional topics include electronic and opto-electronic devices, organic magnets and conductors, lubricants, other materials, and reactions of industrial or biomedical importance. The book concludes by providing an outlook on possible future development in this field. Researchers and practitioners engaged in active work on synthetic or mechanistic organic chemistry and its practical applications will find this text to be invaluable in both its scope and its depth.

Organic Mechanochemistry and Its Practical Applications gathers physical and organic chemistry-based molecular principles, evolving interpretations of scientific data, and real world applications to demonstrate the synthetic advantages of mechanically initiated organic reactions. This book considers transformations of organic substances upon mechanical actions and explains how mechanical energy is transformed into chemical driving force.

The author, a renowned expert in physical and organic chemistry, carefully examines the concurrent chemical and physical processes-particularly polymerization and dynamic shearing-that involve organic substances and inorganic surfaces during lubrication. Dr. Todres discusses the various factors that affect boundary lubrication, such as material properties, chemical reactivity, pressure, and temperature. The book describes conformational transformations and structural phase transitions of organic molecules and working materials that take place under mechanical forces, such as drilling, grinding, friction, and shearing, and shock-waves. Other key topics include mechanochromism, tribopolymerization, mechanical activation of organic reactions, and the peculiarities of catalytic effects in organic mechanochemistry.

Throughout the text, the author highlights novel technical applications of mechanochemical phenomena in a variety of fields, including lubrication, biomedical engineering, pharmaceutical drug formulation, environmental protection, and practical economy. Organic Mechanochemistry and Its Practical Applications reveals how mechanochemistry was inspired by principles in various disciplines to create innovative approaches for current challengesin these fields.

Zory Vlad Todres' monograph offers a fresh insight into an important and developed area of organic chemistry. Calixarene, cyclodextrins, and cucurbiturils as host molecules are well known, but the corresponding new and demonstrative publications deserve new exposition. This book principally widens our consideration of organic reactivity in confining media. Topics discussed include: effects of micellization, porous effects, effects of solvent cages, complexation to organometallic compounds, hydrogen-bond or charge-transfer complexation, sorption effects, effects of solvents, and stereochemical changes upon confinement. Organic Chemistry in Confining Media is useful for experienced organic chemists working in academia or industry, as well as chemists working in fields contiguous to organic chemistry.
