On the Mechanism of Oxetan Formation in the Photocycloaddition of p-Benzoquinone to Alkenes
Photochemical oxetan formation from p-benzoquinone and simple alkenes takes place from the lowest 3n,π* state of the quinone. It is suggested that an exciplex is formed between the alkene and the excited quinone, but that a biradical is nevertheless the immediate precursor of the oxetan.
