On irradiation, phthalimides 4 dissolved in acetonitrile reacted with various olefins 1 to give 5, while the reaction of succinimides with the corresponding olefins resulted in the formation of oxetanes. Photolysis of N-alkenylphthalimides 8 in acetonitrile afforded 9. The presence of N-alkenyl δ,ε double bond (counted from N atom) is extremely preferable for the formation of 9.
