N‐Heterocyclic Carbenes

Angewandte Chemie International Edition in English, 1997
AbstractThe chemistry of N‐heterocyclic carbenes has long been limited to metal coordination compounds derived from azolium precursors, a development that was started by Öfele and Wanzlick in 1968. Since free carbenes are now available through the work of Arduengo (1991), a renaissance in this little‐recognized area of chemistry has occurred. A leading

N-Heterocyclic Carbenes

2016
Abstract This review tries to shed light on the early history of different methods for the generation of N-heterocyclic carbenes (NHCs), i.e., the extrusion of heterocumulenes (decarboxylations) from suitable mesomeric betaines, deprotonations of hetarenium salts, α-eliminations, tautomerizations of mesomeric betaines, and reductive desulfurizations ...

N-Heterocyclic carbenes

Journal of Organometallic Chemistry, 2000
Palladium(0) complexes of N-heterocyclic carbenes (NHC) are easily obtained starting from the free carbene and bis(tri-orthotolylphosphine)palladium(0) by ligand exchange. The complexes [(R)N(H)CC(H)N(R)C ‚„„„„„„„„„” ]2Pd of various 1,3-disubstituted imidazolin-2-ylidenes have been prepared by this method (R mesityl, t-Bu, i-Pr, cyclohexyl).

N‐Heterocyclic Carbenes as Organocatalysts

Angewandte Chemie International Edition, 2007
AbstractOrganocatalyzed reactions represent an attractive alternative to metal‐catalyzed processes notably because of their lower cost and benign environmental impact in comparison to organometallic catalysis. In this context, N‐heterocyclic carbenes (NHCs) have been studied for their ability to promote primarily the benzoin condensation.

Planar tris-N-heterocyclic carbenes

Chemical Communications, 2013
To further explore the coordination chemistry of poly-carbene complexes, two triphenylene-based planar tridentate N-heterocyclic carbenes and their corresponding tri-gold complexes were synthesized. Molecular structures of the tert-butyl substituted tritopic free carbene and the tri-nuclear gold complex were determined experimentally.
