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 …

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 …

N‐Heterocyclic carbenes (NHCs) are commonly prepared by deprotonation of azolium salts
using strong anionic bases. This reaction is often unselective, yielding alkali metal NHC …

A neutral azole precursor to a protic N-heterocyclic carbene (p NHC) ligand, 6-((4, 5-
diphenyl-1 H-imidazol-1-yl) methyl)-2, 2′-bipyridine (3), was prepared from 6 …

A set of ruthenium (II)‐protic‐N‐heterocyclic carbene complexes,[Ru (NNCH)(PPh3) 2 (X)]
Cl (1, X= Cl and 2, X= H) and their deprotonated forms [Ru (NNC)(PPh3) 2 (X)](1', X= Cl 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 …

A family of air-and moisture-stable dinuclear palladium complexes bearing 2-benzimidazolyl
ligands is reported and shown to be a highly effective and general catalytic platform in …

Abstract Neutral 4‐iodo‐N‐ethylimidazole 3 oxidatively adds to [Pt (PPh3) 4] to give, in the
presence of different tetraalkylammonium salts, complexes trans‐[4], trans‐[5], and trans‐[6] …

A nonfunctionalized bis (imidazole) ligand precursor has been directly metalated using
IrCp*(OAc) 2, leading to a mixture of bis (protic N-heterocyclic carbene)(bisPNHC) …
