• The mercury- and cadmium-photosensitized reactions of β-propiolactone (PL) have been investigated. The gaseous products from the mercury-photosensitized reaction were carbon dioxide, ethylene, carbon monoxide, ethylene oxide, acetaldehyde, and methane, while the products obtained in the cadmium-photosensitized reaction were carbon monoxide, ethylene oxide, and acetaldehyde. In the mercury-photosensitized reaction, the quantum yields of the products were independent of the lactone pressure at pressures higher than 1500 Pa, while in the cadmium-photosensitized reaction, the quantum yields of the products decreased with the increase in the lactone pressure. Several possible reaction schemes have been proposed to explain the above kinetic behavior. The mercury- and cadmium-photosensitized reactions proceed through different intermediates, that is, a triplet lactone in the former and an excited complex between an excited cadmium atom and a lactone molecule in the latter.
