Cadmium-photosensitized Reaction of γ-Valerolactone and α-Methyl-γ-butyrolactone

Article abstract of DOI:10.1246/bcsj.58.2038

The cadmium-photosensitized reactions of γ-valerolactone and α-methyl-γ-butyrolactone have been investigated.The obtained products in both cases were carbon monoxide, ethylene, propylene, acetaldehyde, and 2-methyloxetane.The dependence of the yields of ethylene and propylene on the total pressure suggests the existence of a biradical and an energized intermediate.Possible mechanisms are discussed.
