  Photocyclization of aryl vinyl ethers reportedly proceeds via carbonyl ylide intermediates. The photochemical behavior of several aryl vinyl ethers, which incorporate a pendant alkene side chain, was explored. Naphthyl vinyl ethers 1c and 1d provided products that are consistent with photocyclization and subsequent intramolecular ylide-alkene addition. Product distribution is influenced by solvent and temperature effects. Thus, irradiation of 1c in toluene provides 9a in 87% yield. However, irradiation of 1c in methanol/toluene (1:1) provides 3c (45%), 11 (24%), and 12 (23%). Product 12 results from photoinitiated intramolecular [2 + 2] cycloaddition of the butenoate ester side chain to the naphthalene system.

  Photocyclization of aryl vinyl sulfides reportedly proceeds via thiocarbonyl ylide intermediates. The photochemical behavior of several aryl vinyl sulfides, which incorporate a pendant alkene side chain, was explored. In general, naphthyl and phenyl vinyl thioethers provided products which are consistent with photocyclization to a thiocarbonyl ylide intermediate followed by either intramolecular hydrogen shift or subsequent intramolecular ylide-alkene addition. Product distribution is influenced by solvent and temperature effects. Novel secondary photoprocesses were also observed during some reactions. Thus, irradiation of naphthyl vinyl sulfide 20 gave dihydrothiophene 22 which underwent subsequent intramolecular [2 + 2] cycloaddition to provide 24. Upon prolonged irradiation 24 undergoes a novel allylic sulfide rearrangement to provide 25.
