Abstract
NHCs activate a diverse range of materials and thereby play a central role in modern reaction discovery. Our studies have focused on the application of NHCs as Lewis base catalysts. We recently developed an all-carbon [4+2] cycloaddition-decarboxylation that typifies this type of catalysis. Herein, the discovery of this methodology, its context and scope are discussed.
Key words
catalysis - acyl azolium - N-heterocyclic carbenes - cycloaddition - cyclohexadiene
