pentafluorobenzene with cycloalkenes in cyclohexane solution resulted in regioselective 2+2 cycloaddition to the 3,4 position of the arene. The stereochemistry of the products formed depended on the structure of the cycloalkene: only an anti 2+2 adduct was observed with cyclopentene, a syn 2+2 adduct with norbornene, while both syn and anti 2+2 cycloaddition took place with cycloheptene and cyclooctene. The magnitude
