  Direct C–H Bond Arylation of (Benzo)oxazoles with Aryl Chlorides Catalyzed by N-Heterocyclic Carbene–Palladium(II)–1-Methylimidazole Complex

  摘要：

  The direct C-H bond arylation of (benzo)oxazoles with aryl chlorides was achieved catalyzed by a well-defined NHC-Pd(II)-Im complex. Under the optimal conditions, various aryl chlorides were successfully applied as the arylating reagents to achieve the 2-aryl (benzo)oxazoles in acceptable to high yields, providing a convenient and alternative method for the direct C-H bond arylation of (benzo)oxazoles and enriching the chemistry of the NHC-Pd(II) complex in organic synthesis.
