The synthesis of regio- and stereoselective aryl substituted α,β-unsaturated aldehydes and ketones from activated allenes was achieved. This mild and non-metallic oxidation is exclusively driven by benign ambient air and triggered by visible light. The same starting materials under ideal anaerobic conditions led to the 2,3-diphenylselenation adduct with no trace of oxygenated products, demonstrating dissolved oxygen as a chemical switch for two different reaction pathways. The salient feature of this protocol is the single electron transfer (SET) achieved by irradiation of one of two organic molecules thereby avoiding a sensitizer to form a radical ion pair.

Free-radical addition of diphenyl diselenide 2 to allenes 1 took place under irradiation through Pyrex with tungusten lamp to provide 1-(phenylselenomethyl)vinyl selenides 3 in excellent yields.
