The N-heterocyclic carbene-catalyzed intermolecular Stetter reaction of aldehydes with alpha,beta-unsaturated sulfones allows the atom-economic and selective formation of gamma-keto sulfones in good yields. Key to the success of this unique transition-metal-free carbon-carbon bond-forming reaction is the right choice of the NHC precursor and base. The reaction tolerates a broad range of different aldehydes.
