An iron‐promoted electrophilicannulation of arylenynes with disulfides or diselenides has been developed. In the presence of iron(III) chloride (FeCl3) and iodine (I2,), a variety of trifluoromethyl‐containing arylenynes underwent electrophilicannulation with various disulfides or diselenides successfully to afford the corresponding polysubstitutednaphthalenes in moderate to excellent yields.
