Journal ArticleDOI
N-Heterocyclic Carbene-Catalyzed Decarboxylative Alkylation of Aldehydes
TL;DR: It is found that N-heterocyclic carbene catalysis promoted the unprecedented decarboxylative coupling of aryl aldehydes and tertiary or secondary alkyl carboxylic acid-derived redox-active esters to produce ary lkyl ketones.
Journal ArticleDOI
Recent advances in N-heterocyclic carbene-based radical catalysis
TL;DR: This minireview highlights the recent progress and developments in NHC-based radical catalysis and is categorized according to the reaction types; oxidation type reaction and carbon–carbon bond formation through single electron transfer/radical–radical coupling.
Journal ArticleDOI
N-Heterocyclic Carbene-Catalyzed Radical Relay Enabling Vicinal Alkylacylation of Alkenes.
TL;DR: This protocol introduces tertiary alkyl groups and acyl groups to C-C double bonds with complete regioselectivity to produce functionalized ketone derivatives.
Journal ArticleDOI

TL;DR: In this paper, the enolate form of the Breslow intermediate derived from an aldehyde and thiazolium-type NHC in the presence of a base undergoes single electron transfer to an aryl iodide, providing an annealing radical.
Journal ArticleDOI
Synergistic N-Heterocyclic Carbene/Palladium-Catalyzed Reactions of Aldehyde Acyl Anions with either Diarylmethyl or Allylic Carbonates.
TL;DR: Benzylation and allylation of aldehyde acyl anions were enabled by the merger of a thiazolium N-heterocyclic carbene (NHC) catalyst and a palladium/bisphosphine catalyst in a synergistic manner.
