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 ...
