Part 3. Photoreactions of α,β-Unsaturated γ,δ-Epoxy Dinitrile, α-Cyano Ester, and Diester with Various Dipolarophiles. -Photolysis of the dinitrile (I) generates a carbonyl ylide which undergoes 1,3-dipolar cycloaddition with enol ethers [cf. (II)] to give cycloadducts (III) and (IV) in low yields.
