Herein, we describe a novel, green, and efficient synthesis of a series of different substituted osmanaphthalynes (including ‐H, ‐Br, ‐I, ‐CH 3 and ‐CF 3 ) and the first examples of the preparation of α‐osmaanthracyne and α‐osmaphenanthryne by means of a visible light‐induced intramolecular cyclization reaction of their corresponding osmium hydrido alkenylcarbyne complexes. This visible‐light‐driven method provides an efficient and straightforward approach to afford the desired fused metal heterocyclic complexes constructed with an Os atom as the metal center in high yield under mild conditions.
