unprecedented method to the synthesis of 1-azathioxanthone derivatives has been developed by means of palladium-catalyzed C(formyl)-C(aryl) coupling followed by SNAr reaction. Optimization study was carried out through different catalyst, ligand, base and solvent. This approach displays various exclusive characteristics such as operational convenience, moderate to good isolated yields and decent functional
