Free radical reactions have become increasingly important and a very attractive tool in organic synthesis in the last two decades, due to their powerful, selective, specific, and mild reaction abilities. Advanced Free Radical Reactions for Organic Synthesis reviews information on all types of practical radical reactions, e.g. cyclizations, additions, hydrogen-atom abstractions, decarboxylation reactions. The book usefully provides experimental details for the most important reactions as well as numerous references to the original literature. By covering both the fundamentals and synthetic applications it is therefore suitable for both new and experienced researchers, chemists, biochemists, natural product chemists and graduate students. This title is the definitive guide to radical chemistry for all scientists. more...

About the Book: The present compendium on Advanced Practical Medicinal Chemistry is designed specifically to serve as a text-cum-reference book not only intended for the advanced undergraduate and graduate students of Pharmacy specializing in pharmaceutical chemistry but also for the bulk-drug industrial researchers and academics who work intimately with medicinal compounds. It mainly comprises of four comprehensive chapters. First chapter is entirely devoted to Safety in Chemical Laboratory, which is an absolute must for each medicinal chemist. Second chapter is on Drug Synthesis and concentrates on three vital aspects, namely : conceptualization of a synthesis, reaction variants, and stereochemistry. Third chapter exclusively deals with Performing the Reactions and entails the wide range of latest laboratory techniques used in a good chemical laboratory to facilitate synthesis of drugs. Fourth chapter is particularly focused and earmarked to Synthesis of Medicinal Compounds, and essentially include various cardinal aspects, such as :types of chemical reactions, organic name reactions (ONRs), and selected medicinal compounds. A galaxy of eighty carefully chosen medicinal compounds have been presented in an original unique style comprising of: chemical structure, synonym (s)/chemical name(s) theory chemicals required procedure precautions recrystallization theoretical yield/practical yield physical parameters uses, and questions for viva-voce. It is hoped that Advanced Practical Medicinal Chemistry would certainly help to bridge existing gap and fill up the long needed vacuum in the synthesis of drugs in pharmaceutical chemistry departments, academics and bulk-drug industries, and may provide the basis for meaningful productive group discussions of synthetic problems on a broader perspective Contents: Safety in a Chemistry Laboratory Drug Synthesis Performing the Reactions Synthesis of Medicinal Compounds Index. more...

This volume is an account of the various approaches used to improve the toughness of polymer matrices. The correlations among the molecular structure of the components, the morphology and the mechanical properties of blend systems are stressed. Emphasis is placed on the methods used to control the structure of these materials during processing. The book concentrates on a number of systems which may be regarded as typologies of toughened plastics. From an extensive treatment of these systems more general concepts have been developed. These concepts which are indispensable in the design and formulation of tough polymer blends, include the role of the interface in multicomponent systems, the chemical reactivity of the blend components, the mode and state of dispersion of the second phase, the crystallinity and crystallization conditions, the glass transition temperature etc. The long term activity in the area is mainly reported, which started in the early seventies with the chemical modification of ethylene-propylene copolymers to be used as tougheners of Polyamide-6. Such a system is investigated further both from a fundamental and from an applicative point of view. The volume shows how intellectually stimulating and challenging the field of polymer toughening can be, and is intended to encourage the reader to do more research in this area. more...
