Visible-light-photocatalysis driven denitrogenative/radical 1,3-shift of benzotriazole: access to 3-aryl-aminoquinoxalin-2(1H)-one scaffolds

We described a visible-light-photocatalysis driven denitrogenative/radical 1,3-shift of benzotriazole to generate unusual aromatic amine radical which then undergo direct amination with quinoxalin-2(1 H )-ones leading to 3-aryl-aminoquinoxalin-2(1 H )-ones.
