• The photolysis of 4′-(2-phenyl-1,2-dioxoethyl)benzo-15-crown-5 in benzene containing 1-dodecanethiol gives benzaldehyde and 4′-formylbenzo-15-crown-5. The formation of the aldehydes was inhibited by the sodium ion, whereas the photolysis of 1-(3,4-dimethoxyphenyl)-2-phenylethanedione was not inhibited by the sodium ion. This inhibition must be due to the decrease in the formation of benzoyl radicals from the triplet excited state of the crown ether derivative. The salt effect was discussed on the basis of the spectral data.
