Dicyanopyrazine: 10th Anniversary in Photoredox Catalysis. [PDF]
Chem RecThe last decade unveiled dicyanopyrazine as a purely organic photocatalyst capable of initiating a variety of unprecedented photoredox transformations. The latest discoveries also pointed to a facile Mallory‐type photocyclization of the catalyst to quinoxaline‐2,3‐dicarbonitrile derivative, which proved to be the active catalytic species. Its principal
