ketone and the ability of the alkene to stabilize a key radical intermediate. A method for intermolecular [3+2] cycloadditionbetween aryl cyclopropyl ketones and alkenes involving the combination of Lewis acid and photoredox catalysis is reported. In contrast to other more common methods for [3+2] cycloaddition, these conditions operate using a broad range of both electron-rich and electron-deficient
