A direct transformation of ortho‐alkynylated aromatic vinyl ethers to 1‐iodonaphthalenes and other iodo‐heterocycles under mild Lewis acidic conditions in the presence of iodide as an external nucleophile is reported. The first example of an iodoannulation strategy using a nucleophilic source of iodine, coupled with good to excellent yields, exclusive alpha regioselectivity and a broad substrate scope
