Carbenes are important molecules in chemistry because of their photochemistry and high reactivity. They have many potential applications in medicinal and materials chemistry. This book provides a comprehensive introduction to carbenes and discusses their characteristics, structure, and synthesis procedures. It gives special emphasis to N-heterocyclic carbenes (NHCs) and their metal complexes.

This book provides researchers in the fields of organic chemistry, organometallic chemistry and homogeneous catalysis with an overview of recent developments in the applications of reactions involving carbene and nitrene intermediates directed to the synthesis of heterocyclic compounds. Multiple pathways through which diverse heterocyclic compounds are accessed occur from a variety of carbene and nitrene precursors through C-H/X-H insertions, cycloadditions, ylide transformations, rearrangements, and cascade reactions. Catalytic processes that form metallo-carbenes and nitrenes offer unparalleled chemo-, regio-, and stereo-selectivities. Insights are provided into the scope of these methodologies and the inherent control of catalyst ligands on reaction selectivities.

Carola Vogel’s PhD thesis focuses on the synthesis, and structural and spectroscopic characterization of the first high valent iron nitride complexes. In her interdisciplinary and collaborative research Carola also describes the reactivity studies of a unique iron (V) nitride complex with water. These studies show that quantitative yields of ammonia are given at ambient conditions. High valent iron nitride and oxo species have been proposed as key intermediates in many bio-catalytic transformations, but until now these species have proven exceedingly challenging to isolate and study. Iron complexes in high oxidation states can thus serve as models for iron-containing enzymes to help us understand biological systems or aid our development of more efficient industrial catalysts.

It was only in the early 1990s that carbenes with the carbene carbon being incorporated in a nitrogen containing heterocycle (N-heterocyclic carbenes or NHCs) were found to be stable enough to be isolated. Since the first report on the application of NHCs as ligands in transition metal catalysis in 1995, NHC have found numerous applications and have been established as a versatile and indispensable class of ligands. For many reactions like metathesis or cross-coupling reactions NHCs have often become the ligands of choice, allowing otherwise difficult transformations. In this book leading experts have surveyed major areas of application of NHC metal complexes in catalysis. The authors have placed a special focus on nickel- and palladium-catalyzed reactions, on applications in metathesis reactions, on oxidation reactions and on the use of chiral NHC-based catalysts. This compilation is rounded out by an introductory chapter and a chapter dealing with synthetic routes to NHC metal complexes. The use of NHC as ligands in catalysis has reached a certain level of maturity and this book allows the reader to get a balanced view of this increasingly important ligand class.
