title: Photoinduced ortho [2 + 2] cycloaddition of double bonds to triplet benzenes.
abstract: The triplet states of certain phenyl ketones and benzoic acid derivatives undergo regioselective and stereoselective intramolecular ortho cycloaddition to remote double bonds, triggering an array of photochemical and thermal pericyclic rearrangements among various novel polycyclic products.
