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.

An overview of N-heterocyclic carbenes

Nature, 2014
The successful isolation and characterization of an N-heterocyclic carbene in 1991 opened up a new class of organic compounds for investigation. From these beginnings as academic curiosities, N-heterocyclic carbenes today rank among the most powerful tools in organic chemistry, with numerous applications in commercially important processes.

N-Heterocyclic carbenes in gold catalysis

Chemical Society Reviews, 2008
The appealing properties of N-heterocyclic carbenes (NHC) as ancillary ligands and the high potential of gold as an organometallic catalyst have made their encounter inevitable. Still in its infancy, NHC-gold catalysis is nevertheless growing rapidly.
