Palladium-Catalyzed Oxidative C—H/C—H Cross-Coupling of Benzothiazoles with Thiophenes and Thiazoles

A concise palladium-catalyzed method for oxidative C–H/C–H cross-coupling between benzothiazoles and thiophenes/thiazoles has been developed. This CDC reaction is insensitive to air and moisture with high functional group tolerance.
