N-Heterocyclic Carbenes: An Introductory Overview

摘要: N-heterocyclic carbenes (NHCs) are probably the class of ligands that not only has attracted most attention during past decade, but also for which greatest advances have been made. These include a wider availability, applicability and understanding. In this chapter, an overview all aspects NHCs is given, starting with historical discussion begins almost century ago. An inventory structural diversity found in literature followed by nomenclature trivial names used. A section devoted to synthetic strategies developed formation NHC-precursors, NHC NHC-complexes. The diagnostic spectroscopic features complexes listed as well manner usually represented. become indubitably one important unique they very distinctive interesting electronic steric features. large chapter hence these presents recent made determination properties their
