Since the discovery of the first stable N-heterocyclic carbene (NHC) in the beginning of the
1990s, these divalent carbon species have become a common and available class of …

N-Heterocyclic carbenes (NHCs) have become without doubt one of the most exciting and
popular species in chemical science due to the ease of their preparation and modularity in …

Luminescent complexes of heavy metals such as iridium, platinum, and ruthenium play an
important role in photocatalysis and energy conversion applications as well as organic light …

N-Heterocyclic carbenes (NHC) are nowadays ubiquitous and indispensable in many
research fields, and it is not possible to imagine modern transition metal and main group …

This review considers phosphine and N-heterocyclic carbene complexes of gold (I) that are
used as (pre) catalysts for a range of reactions in organic synthesis. These are divided …

Abstract Discovered in 2005, cyclic (alkyl)(amino) carbenes (CAACs) are among the most
nucleophilic (σ donating) and also electrophilic (π‐accepting) stable carbenes known to …

Ligands, especially phosphines and carbenes, can play a key role in modifying and
controlling homogeneous organometallic catalysts, and they often provide a convenient …

Carbenes have evolved from transient laboratory curiosities to a robust, diverse, and
surprisingly impactful ligand class. A variety of different carbenes have significantly …

Cyclic (alkyl)-and (aryl)-(amino) carbenes (CAACs and CAArCs) are stronger σ-donors and
π-acceptors than imidazol-2-ylidenes and imidazolidin-2-ylidenes, the well-known N …

Conspectus Carbenes are compounds that feature a divalent carbon atom with only six
electrons in its valence shell. In the singlet state, they possess a lone pair of electrons and a …
