1.1.2 Types of N-Heterocyclic Carbenes

View through CrossRef
AbstractThis chapter discusses the different types of N-heterocyclic carbenes (NHCs) and is organized according to ring size. The terminology for describing NHCs as normal or abnormal (mesoionic) and remote or nonremote is outlined. The pertinent properties of these different NHCs are compiled, in particular the 13C NMR spectroscopic and crystallographic parameters, as well as steric and electronic effects, which provides insights into the donor properties of the various classes of NHCs.
