Much data has been collected from experiments on the kinetios of radical reactions in different solids, but to date, this has not been presented in book format in a thorough and comprehensive way. This book makes the experimental data accessible for all chemists involved in these reactions. Various models of the tunnel atom transfer are analyzed in order to explain the kinetic isotope effect in solid phase reactions and photoinitiated radical reactions are inspected for the kinetic non-equivalence of particles and factors affecting their reactivity.Topics covered include: kinetic description of reactions with dispersion particles in reactivitythe influence of space-orientation factors on reactivity in cage reactionsthe influence of molecular dynamics on the kinetics of elementary reactionsthe effect of structural-physical modification on kinetics of cage radical reactions

Oxidation of Organic Compounds: Medium Effects in Radical Reactions explores the role of solvents and of the composition of phase states in radical-chain processes involved in the oxidation of organic compounds. Organized into 10 chapters, this book begins with a discussion of the basic concepts relating to the mechanism involved in the oxidation of hydrocarbons and other organic compounds in liquid-phase reactions. Subsequent chapters detail some methods for studying the mechanism of oxidation reactions; role of solvation in chemical reaction kinetics; role of the medium in chain-initiation reactions; role of non-specific and specific solvation in chain-propagation and chain-termination reactions; and the role of solvation in chain-termination reactions in inhibitors. The influence of the solvent and the phase state of substances undergoing oxidation on the rates and mechanisms of individual elementary processes are also addressed. The last chapter examines the problem of the influence of the solid state of the polymer on the reactivity of radicals. This monograph will be valuable to scientific research workers, engineers, and engineering technologists specializing in the field of radical reactions and in particular in the oxidation of organic compounds.

Chemistry of the O-glycosidic Bond: Formation and Cleavage focuses on the compositions, characteristics, formation, and reactions of O-glycosidic bonds, including the synthesis of oligosaccharides and polysaccharides. The publication first offers information on the characteristics and formation of O-glycosidic bonds, as well as the Fischer, Koenigs-Knorr, orthoester, and oxazoline methods. The text also looks at the synthesis of oligosaccharides. Concerns include evaluation of methods of glycosylation from the oligosaccharide synthesis viewpoint; stepwise propagation of oligosaccharide chains; and synthesis of disaccharides and higher oligosaccharides. The manuscript analyzes the synthesis of polysaccharides, including polycondensation, cationic polymerization, and synthesis of branched polysaccharides from linear ones. The book also reviews miscellaneous glycoside synthesis and cleavage of O-glycosidic bonds. Topics include synthesis of sugar anhydrides and aryl glycosides and acid-catalyzed hydrolysis. The text is a dependable reference for readers interested in O-glycosidic bonds.
