An efficient photo‐Bergman reaction of aliphatic enediynes has been realized. Photolysis of 1 results in the formation of 4 in good yields along with [D 2 ] 3 . Enediyne 4 , which has never been isolated in the thermal reaction of 1 , arises here by a retro‐Bergman reaction of the diradical intermediate 2 .
