Science of Synthesis: Cross-Dehydrogenative Coupling by Debabrata Maiti Pdf

Comprehensive overview of strategies and applications of cross-dehydrogenative coupling methods Cross-Dehydrogenative Coupling (CDC) represents a type of coupling reaction for the construction of a C−C bond or C−heteroatom (C–X) bond directly from C−H and X−H bonds present in the precursors. Since this genre of coupling reaction obviates the need for substrate prefunctionalization, it has an added advantage of high efficiency, atom economy, and environmental friendliness. CDC reactions are triggered by transition-metal catalysts or simply by an oxidants, or by either photocatalysis or electrocatalysis, leading to a hetero- or homo-coupled products with the removal of two hydrogens. Over the years, several CDC strategies have been developed that has made it possible to construct bonds between carbon-hydrogen (C–H) bonds of diverse hybridization. CDC has also streamlined the synthesis and functionalization of various nitrogen, oxygen, and sulfur-containing heterocycles. This volume features a series of chapters systematically covering methods and strategies in CDC, organized primarily on the type of bond being formed. In addition, particular aspects of CDC are highlighted in devoted chapters on topics such as mechanistic aspects, electrochemical and flow methods, transformations in water, natural product synthesis, and enantioselective protocols.

Noncovalent Interactions in Catalysis by Kamran T Mahmudov,Maximilian N Kopylovich,M Fatima C Guedes da Silva,Armando J L Pombeiro Pdf

Noncovalent interactions often provide the spine of biomolecular and material structures, and can therefore play a key role in biological and catalytic processes. Selectivity in chemical reactions, particularly in catalytic processes, is often an orchestral action of various noncovalent interactions occurring in intermediates and transition states. Although the role of hydrogen bonding is well explored in catalysis, the other types of weak interactions, namely cation–π, anion–π, π–π stacking, pseudo-agostic, halogen, chalcogen, pnictogen, tetrel and icosagen bonds, must also be considered. Naturally, the chemo-, regio- or stereoselectivity of a reaction depends on the stability of such noncovalent-interaction-supported species in catalytic systems. Therefore, an in-depth understanding of these weak interactions may be the key to designing new catalytic materials. Providing an overview of the role of these different types of noncovalent interactions in both homogenous and heterogeneous catalysis, this book is a valuable resource for synthetic chemists who are interested in exploring and further developing noncovalent-interaction-assisted synthesis and catalysis.
