Highly efficient, one-step synthesis of sulfur-containing heteroacenes was achieved through palladium-catalyzed C?S cross-coupling of bis-alkynes with thioacetate as hydrogen sulfide surrogate. Heteroacenes consisting of three, five, and seven fused aromatic rings were obtained in a single catalytic step by four-, six-, and eightfold C?S bond formation.
