metal‐free and chemoselective oxidative intramolecular coupling of arene and alkene C−H bonds is reported. The active hypervalent iodine (HVI) reagent, generated catalytically in situ from iodotoluene and meta‐chloroperoxybenzoic acid (m‐CPBA), reacts with o‐vinylbiphenyls to generate polyaromatic hydrocarbons in up to 95 % yield. Experimental evidence suggests the reactions proceed though vinyliodonium
