Direct arylation of benzoxazole C–H bonds with iodobenzene diacetates

A Pd (OAc)2-catalyzed direct arylation of benzoxazole C–H bonds has been achieved with iodobenzene diacetates as the arylation reagent in moderate to good yields. The procedure tolerates a series of functional groups, such as methoxy, nitro, cyano, chloro, and bromo groups.
