The book "N-Heterocyclic Carbenes in Transition Metal Catalysis" offers a comprehensive examination of the role of N-Heterocyclic Carbenes (NHCs) as ligands in transition metal catalysis. Since their discovery in the 1990s, NHCs have established themselves as stable and versatile ligands used in a variety of reactions, including metathesis and cross-coupling reactions. The authors, leading experts in the field, highlight the key application areas of NHC-metal complexes in catalysis, with a particular focus on nickel- and palladium-catalyzed reactions as well as the use of chiral NHC-based catalysts. The book also includes an introductory chapter and discusses synthetic routes to NHC-metal complexes. It provides readers with a balanced perspective on this increasingly significant class of ligands and their relevance in modern catalysis.
