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 …

Since the discovery of persistent carbenes by the isolation of 1, 3-di-l-adamantylimidazol-2-
ylidene by Arduengo and coworkers, we witnessed a fast growth in the design and …

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 …

Since the discovery of the first air stable NHC, this class of compounds has been intensively
studied and applied in organometallic chemistry and homogeneous catalysis due to the …

This review summarizes the recent progress in the field of S-functionalized N-heterocyclic
carbene ligands and their metal complexes. The syntheses of the azolium precursors and of …

Direct dehydrogenative silylation of pyridyl and iminyl substrates with triethylsilane was
achieved using (L) Ir (cod)(X)(1)(L= a perimidine-based carbene ligand, X= OAc and …

Bis-NHC precursors composed of an azolium and a 2-halogenoazole group connected by
different linkers have been site-selectively metallated to give heterobimetallic complexes …

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 …

The chemistry of N‐heterocyclic carbenes (NHCs) is dominated by N, N′‐dialkylated or‐
diarylated derivatives. Such NHC ligands are normally obtained by C2‐deprotonation of …

Complexes bearing “protic” N‐heterocyclic carbene (NHC) ligands (NR, NH‐NHCs) have
been shown to use the N H group of the NHC ligand for the formation of hydrogen bonds to …
