The employment of N-heterocyclic carbenes (NHCs) to design luminescent metal
compounds has been the focus of recent intense investigations because of the strong σ …

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 …

Carbenes (R2C:), compounds with a divalent carbon atom containing only six valence shell
electrons, have evolved into a broader class with the replacement of the carbene carbon or …

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

The usage of carbon monoxide (CO) as a C1 feedstock for carbonylation has been an
important subject of numerous studies for over a century. The chemistry in this field has …

The use of N-heterocyclic carbenes (NHCs) in chemistry has developed rapidly over the
past twenty years. These interesting compounds are predominantly employed in …

The research on 1, 2, 3-triazoles has been lively and ever-growing since its stimulation by
the advent of click chemistry. The attractiveness of 1H-1, 2, 3-triazoles and their derivatives …

Beyond the Tolman electronic parameter: The 31P NMR chemical shifts of easily
synthesized carbene–phenylphosphinidene adducts allow the determination of the relative …

Three different structural classes of NHC ligands can be distinguished: normal (nNHC),
abnormal (aNHC), alternatively called mesoionic (MIC), and remote (rNHC). General …

Shortly after their discovery at the end of the 80s, stable singlet carbenes have been
recognized as excellent ligands for transition metal based catalysts, and as organo-catalysts …
