A facile transition-metal-free decarboxylative radical coupling reaction of ,-difluoroarylacetic acids with quinoxalin-2(1H)-ones has been developed. This methodology provided a highly attractive approach to synthesize a series of difluoroarylmethylated quinoxalin-2(1H)-ones that contain various functional groups in moderate to good yields under mild conditions. Moreover, experimental studies reveal that the CF2 group of ,-difluoroarylacetic acids plays a vital role in this transformation.
