Alkene moiety can act as a directing group as well as a reaction site and achieved the regioselective cleavage of a sterically more hindered C−C bond of 1‐substituted biphenylenes. The cationic rhodium catalyst facilitated an intramolecular reaction of 1‐(2‐vinylaryl) biphenylenes to give a new carbon skeleton of dihydrobenzo[ b ]fluoranthene.
