摘要: A highly efficient transition metal-free oxidative chemo- and regioselective C–C bond coupling of pyrazolones quinoxalinones mediated by K2S2O8 is described. This reaction can be conveniently carried out under mild conditions gives various hydroxy-pyrazolyl quinoxalinone products in moderate to excellent yields a short time.
