Science of Synthesis: Metal-Catalyzed Cyclization Reactions Vol. 2

Группа авторов

Significant advances in metal-catalyzed reactions, especially cyclizations, have dramatically improved the efficiency of organic synthesis over the last three decades. To date these transformations are widely used in the area of synthesis of both natural products and therapeutic agents. «Science of Synthesis: Metal-Catalyzed Cyclization Reactions» presents the most commonly used and significant metal-catalyzed reactions for modern organic synthesis. The basic principles, the current state of the art, scope, limitations, and mechanism of these reactions are also discussed. Typical examples of target synthesis are provided to help inspire further applications. Volume 2 covers epoxidations, aziridinations, cyclopropanations, and Pauson-Khand reactions, as well as a wide range of cycloaddition processes, radical cyclizations, and ring-closing metathesis.

Applications of Domino Transformations in Organic Synthesis, Volume 2

Группа авторов

The rapid pace of evolution in domino, or cascade-based transformations has revolutionized the practice of chemical synthesis for the creation of natural products, designed molecules, and pharmaceuticals. «Science of Synthesis: Applications of Domino Transformations in Organic Synthesis» explores the topic thoroughly and systematically, serving as the basis for practical applications and future research. The 2-volume set presents the cutting-edge in terms of design, strategy, and experimental procedures, leading to multiple events being accomplished within a single reaction vessel. The content is organized by the core type of reaction used to initiate the event, be it a pericyclic reaction, a metal-mediated transformation, radical chemistry, or an acid-induced cascade among many others. Volume 1 covers polyene/cation-pi cyclizations, metathesis, radical, and metal-mediated reactions, and non-radical skeletal rearrangements.

Science of Synthesis: Catalytic Transformations via C-H Activation Vol. 2

Группа авторов

The reference work «Science of Synthesis: Catalytic Transformations via C-H Activation» covers the state of the art in C-H activation chemistry. Experts in the field present the best synthetic methods including typical or general experimental procedures. As such, this two volume set can serve as both a basis for the practical application of the techniques discussed, and as an educational resource to lay the foundations for future research. Volume 2 concerns the formation of C-C bonds by C-H activation of non-(het)arene substrates as well as C-H activation using special reagents or techniques. The formation of C-heteroatom bonds by predominantly arene C-H activation is also reviewed. For C-C bond formation, the material is subdivided into allylic, alkyl, and double C-H activation techniques, coupling using carbenes or radicals, and carbonylation or carboxylation processes.

The reference work «Science of Synthesis: Catalytic Transformations via C-H Activation» covers the state of the art in C-H activation chemistry. Experts in the field present the best synthetic methods including typical or general experimental procedures. As such, this two volume set can serve as both a basis for the practical application of the techniques discussed, and as an educational resource to lay the foundations for future research. Volume 1 concerns the formation of C-C bonds by both arene and hetarene C-H activation. For the arenes the material is subdivided into arylation (using palladium(0), palladium(II)/palladium(IV), palladium(II), and ruthenium(II) catalysts), vinylation (using various palladium and ruthenium(III) catalysts), and alkylation (using various metal catalysts in combination with either functionalized alkanes or alkenes). For the hetarenes, the related coupling strategies are covered as a single topic using a variety of metal catalysts and coupling partners.

Ionization and Ion Transport

David B. Go

The purpose of this text is to introduce engineering and science students to the basic underlying physics and chemistry concepts that form the foundation of plasma science and engineering. It is an accessible primer directed primarily at those students who, like the general public, simply do not understand exactly what a plasma or gas discharge is nor do they even necessarily have the fundamental background in statistical thermodynamics, gas dynamics, fluid dynamics, or solid state physics to effectively understand many plasma and gas discharge principles. At the conclusion of this text, the reader should understand what an ion is, how they move, the equations we use to describe these basic concepts, and how they link to the aforementioned topics of plasmas and gas discharges. This book is focused on specific concepts that are important to non-equilibrium, low temperature gas discharges. These discharges find wide applicability today and are of significant interest to the scientific and engineering communities.
