The facile synthesis of new sulfur‐containing fused heterocycles was achieved by a two‐fold domino reaction consisting of a carbon‐sulfur cross‐coupling, followed by a 5‐endo‐dig cyclization. Using this strategy a series of benzo‐, thiopheno‐, pyridine‐ and pyrazino‐dithienoacenes with electron‐neut...
