N-Heterocyclic carbenes (NHCs) have become without doubt one of the most exciting and
popular species in chemical science due to the ease of their preparation and modularity in …

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 use of N-heterocyclic carbenes (NHCs) in chemistry has developed rapidly over the
past twenty years. These interesting compounds are predominantly employed in …

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 …

Mesoionic carbenes (MICs) of the 1, 2, 3-triazolylidene type have established themselves as
a popular class of compounds over the past decade. Primary reasons for this popularity are …

Over the last decades, porphyrin sensitizers have made a remarkable contribution to
performance improvement in dye-sensitized solar cells (DSSCs). In particular, versatile push …

We report the synthesis of acyl azolium salts stemming from thiazolylidenes CNS,
triazolylidenes CTN, mesoionic carbenes CMIC and the generation of their corresponding …

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

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 …

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