A C—H sulfurated cyclization protocol starting from thioacetates is developed for straightforward construction of sulfur‐containing benzoheterocyclics. The diversiform functional dihydrobenzothiophenes and thiochromans were comprehensively achieved through the Pd‐catalyzed carbon‐ sulfur cyclization. Mechanistic studies indicated that C—H bond cleavage was involved in the rate‐determining step. [1]Benzothieno‐[3
