  Pd(0)-Catalyzed Diarylation of sp³C−H Bond in (2-Azaaryl)methanes

  摘要：

  A highly efficient and selective palladium-catalyzed diarylation of (2-azaaryl)methanes at the methyl group is described. Aryl chlorides proved reactive enough. A palladium eta(3)-azaallyl intermediate has been identified on the basis of DFT studies.

  Reactions of 2-carbonyl- and 2-hydroxy(or methoxy)alkylbenzimidazoles with arenes in the Brønsted superacid TfOH resulted in the formation of the corresponding Friedel–Crafts reaction products, 2-diarylmethyl and 2-arylmethyl-substituted benzimidazoles, in yields up to 90%. The reaction intermediates, protonated species derived from starting benzimidazoles in TfOH, were thoroughly studied by means

  2-羰基-和2-羟基（或甲氧基）烷基苯并咪唑与芳烃在布朗斯台德超强酸TfOH中反应，形成相应的弗里德尔-克来福特反应产物，2-二芳基甲基和2-芳基甲基取代的苯并咪唑，产率高达90%。通过 NMR 和 DFT 计算对反应中间体（源自 TfOH 中起始苯并咪唑的质子化物质）进行了深入研究，并讨论了合理的反应机理。
