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 isolation and crystallographic characterization of the first stable N-heterocyclic
carbene in early 1991, 1 nucleophilic diaminocarbenes (also known as “Arduengotype” …

This review summarises the most recent advances in Ir–NHC catalysis while revisiting all the
classical reactions in which this type of catalyst has proved to be active. The influence of the …

A series of lithium complexes of anionic N-heterocyclic carbenes that contain a weakly
coordinating borate moiety (WCA-NHC) was prepared in one step from free N-heterocyclic …

A series of neutral and cationic rhodium and iridium (I) complexes based on hemilabile O-
donor-and N-donor-functionalized NHC ligands having methoxy, dimethylamino, and …

The preparation of the novel N-heterocyclic carbene ligand 3 based on an oxalamide
backbone is described. Carbene 3 is not stable as a monomeric species at ambient …

A new technique is developed that allows one to carry out the signal amplification by
reversible exchange (SABRE) experiments at high magnetic field. SABRE is a …

A novel variant of an iridium‐based organometallic catalyst was synthesized and used to
enhance the NMR signals of pyridine in a heterogeneous phase by immobilization on …

To investigate effects of redox-active functional groups on the coordination chemistry and
electronic properties of N-heterocyclic carbenes (NHCs), we prepared a series of complexes …

High yielding syntheses of 1‐(ferrocenylmethyl)‐3‐mesitylimidazolium iodide (1) and 1‐
(ferrocenylmethyl)‐3‐mesitylimidazol‐2‐ylidene (2) were developed. Complexation of 2 to …
