  N-Heterocyclic Carbene-Catalyzed Cross-Coupling of Aromatic Aldehydes with Activated Alkyl Halides

  摘要：

  N-Heterocyclic carbene-catalyzed umpolung of aldehydes followed by their interception with diarylbromomethanes has been reported. This conceptually novel transition-metal-free cross-coupling of aldehydes with alkyl halides works well at low catalyst loadings and under mild reaction conditions leading to the formation of diaryl acetophenone derivatives in good yields. In addition, a-halo ketones and esters can also be used, as aldehyde reaction partners.

  Acetophenone and deoxybenzoin derivatives are selectively α‐arylated using a combination of very small amounts of palladium acetate and diphenylphosphine oxide as catalyst system and water as the only solvent. Target di‐ and triarylethanones are isolated virtually free of metal residues, and the reaction is amenable to gram‐scale. A mechanistic proposal based on TEM images, poisoning experiments, kinetic

  An efficient regioselective protocol for the C–C bond formation by the unexpected α,α-diarylation of aromatic ketones with unactivated arenes in the presence of selenium dioxide and boron trifluoride etherate has been developed. The generality and functional tolerance of this protocol is demonstrated by the synthesis of a series of triarylethanones.
