Influence of the Localization of the Excitation Energy on the Photochemistry of α,β-Epoxy Ketones

Depending on the localization of the energy, photolysis of α-epoxy ketones excited in their triplet state leads to β-diketones, α-diketones, or fragmentation products.Absorption spectra of ylide intermediates and phosphorescence spectra of α-epoxy ketones are reported.
