Mesoionic carbenes are a subclass of the family of N-heterocyclic carbenes that generally
feature less heteroatom stabilization of the carbenic carbon and hence impart specific donor …

This personal account summarizes our work, beginning with the discovery of the first stable
carbene in 1988 up until the recent isolation of mesoionic carbenes. It explains why we have …

During the last two decades, stable carbenes,[1, 2] especially N-heterocyclic carbenes
(NHCs)(A), have been widely used as ligand for transition-metal complexes.[3] Among their …

Three different structural classes of NHC ligands can be distinguished: normal (nNHC),
abnormal (aNHC), alternatively called mesoionic (MIC), and remote (rNHC). General …

Presents the most innovative results in carbene chemistry, setting the foundation for new
discoveries and applications The discovery of stable carbenes has reinvigorated carbene …

N-Heterocyclic carbenes, despite being isolated and characterized three decades ago, still
capture scientists' interest as versatile, modular and strongly coordinating moieties. In the …

N-Heterocyclic carbenes (NHCs) are nowadays ubiquitous and indispensable as ancillary
ligands in organotransition metal chemistry, with an enormous variety of NHC types known …

Since the discovery of a stable “bottleable” N-heterocyclic carbene (NHC), there has been a
spectacular explosion of interest in this ligand class. This interest stems from a desire to …

Conspectus Since the first reported isolation of a carbene just over a quarter century ago,
the study of such compounds including stable derivatives has flourished. Indeed, N …

Conspectus Classical carbenes are usually described as neutral compounds featuring a
divalent carbon with only six electrons in their valence shell. It was only in 1988 that our …
