The first examples of anionradical cycloaddition induced by homogeneous electrontransfer from chemical agents are described. Specifically, upon exposure to chrysene anionradical, bis(enone) substrates are found to engage in stereoselective intramolecular [2 + 2] cycloaddition. These studies, along with the corresponding electrochemically initiated reactions, provide insight into this fundamentally
