(Chemical Equation Presented) In N-heterocyclic carbene (NHCs) catalyzed nucleophilic substitution of fluorobenzenes, fluoro groups are replaced by aroyl groups, which are derived from aromatic aldehydes. 1,3,4,5-Tetramethylimidazol- 2-ylidene is found to be an efficient catalyst. The catalyst loading can be reduced to 1 mol % without a significant decrease in the product yields. Polysubstituted benzophenones are synthesized from fluorobenzenes and benzaldehydes by the NHC-catalyzed aroylation.

We report for the first time a novel support of polyetheretherketone fiber for the synthesis of recyclable N-heterocyclic carbene (NHC) catalysts. The fiber catalysts were verified in nucleophilic acylation of fluorobenzenes with superior catalytic activities, and successfully recycled by a tiny pair of tweezers over 21 cycles with minimal loss of performance.

experimental part, p. 3960 - 3967 (2011/07/06)
The total synthesis of atroviridin has been accomplished by a linear route involving the N-heterocyclic carbene (NHC)-catalyzed aroylation of the fluorobenzene derivative, Claisen cyclization of the O-propargylated benzophenones, and intramolecular 1,4-addition of the quinone intermediates. The result provides a viable route to xanthone natural products.
