Self-assembled aggregates of 7,10-dibromo-2,3-dicyanopyrazinophenanthrene which act as a new organophotocatalyst in combination with Ni catalyst for the C-aryl-O-acyl cross-coupling reactions of carboxylic acids with aryl halides are described. This visible-light-induced C-aryl-O-acyl bond-formation...
