N-Heterocyclic carbenes (NHCs) are cyclic carbenes bearing at least one R-amino
substituent. 1 The most common subclasses of NHCs are represented in Chart 1. Early work …

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 …

Berylliant! Die Wechselwirkung eines Addukts aus MeBeH und einem N‐heterocyclischen
Carben (NHC) mit PhSiH 3 führt zum vollständigen Bruch des Heterocyclus und zur …

Abstract A cyclic (alkyl)(amino) carbene (CAAC) was found to undergo unprecedented
rearrangements and transformations of its core structure in the presence of Group 1 and 2 …

C− N bond activation of the N-heterocyclic carbene 1, 3-diisopropyl-4, 5-dimethylimidazol-2-
ylidene occurs with Ru (PPh3) 3 (CO) HCl to give the C-2 bound 1-isopropyl-4, 5 …

Abnormal carbene ligand formation from a free monodentate N-heterocyclic carbene, 1, 3-di-
tert-butyl-2-imidazolylidene occurs by coordination of the ruthenium centers to C4-position …

Some new N, N '-bis (aryl) imidazolinium salts (3a− h), in which the N-aryl groups have one
unsubstituted ortho position and alkyl (Me, Pr i) or alkoxy (OMe, OPr i) substitution at the …

Disclosed herein is the unique conjugative role of N-heterocyclic carbene (NHC) ligands as
a directing group in aromatic C–H activation, coupled with a facile NHC–alkenyl annulative …

A combination of experimental studies and density functional theory calculations is used to
study C− N bond activation in a series of ruthenium N-alkyl-substituted heterocyclic carbene …
