Abstract
An efficient palladium–copper-catalyzed direct C–H amination of substituted benzoxazoles with various sulfamoyl chlorides as nitrogen group sources has been developed. The system does not need a strong base and tolerates a series of functional groups, such as chloro, methyl, and nitro groups, providing the amination products in moderate to excellent yields.
