Transition-Metal-Catalyzed C-H Functionalization of Heterocycles A comprehensive guide to recent advances in this field Constituting the majority of all known compounds, heterocycles are structures that incorporate one or more heteroatoms within their core, thus exhibiting properties that are quite different from their all-carbon analogs. They are fundamental to all fields of chemistry and, therefore, their synthesis and modification has attracted a great deal of attention in the recent years. In this vein, transition-metal-catalyzed C-H bond functionalization forms a crucial tool for generating and analyzing heterocyclic compounds. Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, Two-Volume Set, showcases diverse C-H functionalization methodologies and their incorporation into the latest research. The chapters serve as an essential tool depicting detailed site-selective functionalization of heterocyclic cores, along with a comprehensive discussion on their mechanistic approaches. Readers of Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, Two-Volume-Set will also find: <ul><li> A detailed introduction to C-H activation along with the mechanistic aspects of transition-metal-catalyzed C-H bond activation reactions</li> <li> Easy-to-use structures with each chapter dedicated to a type of heterocycle and its specific functionalization methodologies</li> <li>A leading team of international authors in C-H bond functionalization</li></ul> Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, Two-Volume-Set is a valuable guide for students and researchers in organic synthesis and process development, in both academic and industrial contexts.
