Abstract A transition metal‐free direct C‐3 arylation of quinoxalin‐2(1 H )‐ones with arylamines has been explored. This reaction proceeded smoothly through a radical process under mild conditions and produced the desired arylation products in good yields. The reactions proceeded efficiently with a broad range of substrates and functional group tolerance. magnified image
