Homologation of Alkenyl Carbonyls via a Cyclopropanation/Light‐Mediated Selective C−C Cleavage Strategy

We report herein our studies on the direct photoactivation of carbonyl cyclopropanes to give biradical intermediates, leading to selective cleavage of the more substituted carbon‐carbon bond. Depending on the substrate structure, extended alkenes were isolated or directly reacted in a photo‐Nazarov...
