A strategy for synthesis of β‐aryl‐α‐naphthols has been established through an iron‐promoted domino C(sp 3)−H/C(sp )−H and C(sp 2)−H/C(sp )−H dehydrogenative coupling of deoxybenzoins and alkynes. The synthesis uses inexpensive materials with a broad substrate scope and features simple operations with excellent regioselectivity. This study provides an alternative access to various β‐aryl‐α‐naphthols
