Transition metal-catalyzed C-H activation as a route to structurally diverse di(arylthiophenyl)-diketopyrrolopyrroles

Dithiophenyldiketopyrrolopyrroles can be directly (hetero)arylated in moderate to excellent yields by Pd-catalyzed coupling to the CH position of a fluoro(hetero)arene (in the presence of Ag2CO3) or the CBr position of a bromo(hetero)arene.
