The photolysis of the mono substituted cyclic carbonate ester 4‐phenyl‐1,3‐dioxolan‐2‐one has been studied. The direct irradiation results in loss of carbon dioxide with the formation of the corresponding ox‐irane, styrene oxide as well as phenylacetaldehyde and bibenzyl. Photolysis in methanol produces the same compounds in addition to phenethyl alcohol and 2‐methoxy‐2‐phenylethanol. Triplet sensitized photolyses resulted in the products derived entirely from benzyl radicals with none of the oxirane being detected.
