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 …

The research on 1, 2, 3-triazoles has been lively and ever-growing since its stimulation by
the advent of click chemistry. The attractiveness of 1H-1, 2, 3-triazoles and their derivatives …

The use of bis (NHC) manganese (I) complexes 3 as catalysts for the hydrogenation of
esters was investigated. For that purpose, a series of complexes has been synthesized via …

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

This tutorial explores the diversity and characteristics of C-donor ligands. Particular
emphasis is put on the conceptual design of the electronic properties for applications in …

The success of homogeneous catalysis can be attributed largely to the development of a
diverse range of ligand frameworks that have been used to tune the behavior of various …

The organometallic chemistry of N-heterocyclic carbenes (NHCs) has experienced
explosive development during the last few years, and the topic remains the main focus of …

Triazolylidenes have rapidly emerged as a powerful subclass of N-heterocyclic carbene
ligands for transition metals. They are readily available through regioselective [2+ 3] …

Complexes of metals with N-heterocyclic carbene ligands (M/NHC) are typically considered
the systems of choice in homogeneous catalysis due to their stable metal–ligand framework …

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 …
