N-Heterocyclic carbenes (NHCs) are omnipresent ligands in coordination and
organometallic chemistry, which is reflected by myriads of applications involving NHC …

Complexes bearing protic N-heterocyclic carbenes (protic NHCs, pNHCs), defined as cyclic
carbenes stabilized by two heteroatoms including at least one NH group, have been less …

This tutorial review summarizes all works and highlights recent advances published in the
growing field of group 7 N-heterocyclic carbene (NHC) complexes. It provides a valuable …

Though N2 cleavage on K-promoted Fe surfaces is important in the large-scale Haber–
Bosch process, there is still ambiguity about the number of Fe atoms involved during the N …

The review describes methods for the preparation of complexes bearing protic NHC ligands,
ie NHCs featuring an NH, NH or NH, NR substitution pattern. The protic NHC ligands are …

The modular construction of ligands around an N-heterocyclic carbene building block
represents a flexible synthetic strategy for tuning the electronic properties of metal …

This Minireview provides an overview of the chemistry of pyrazole and N‐heterocyclic
carbene (NHC) complexes bearing an NH group at the β‐position to the metal. The …

The oxidative addition of 2-chloro-N-methylbenzimdazole to complexes of type [M (PPh3) 4]
yields after N-protonation compounds with NH, NMe-substituted NHC ligands. For M= Pd …

The N-alkyphosphine-substituted benzimidazoles 5 (R= methylenedicyclohexylphosphine),
7 (R= ethylene-di (t Bu) phosphine), and 8 (R= ethylenedicyclohexylphosphine) have been …

Next to complexes bearing N, N′-dialkylazolium-derived N-heterocyclic carbenes (NR, NR-
NHCs), the coordination chemistry of protic NHC ligands (NH, NR-NHCs and NH, NH …
