Sažetak
Irradiation of 2-[2-(2-vinylphenyl)ethenyl]furan (1a) and 5-methyl-2-[2-(2-vinylphenyl)ethenyl]furan (1b) gave 9, 10-dihydro-4, 9-methano-4H-benzo[4, 5]cyclohepta[1, 2-b]furan (2a) and 9, 10-dihydro-2-methyl-4, 9-methano-4H-benzo[4, 5]cyclohepta[1, 2-b]furan (2b), respectively, in a very good yield in addition to traces of 5. Contrary to these results, the 5-substituted furan derivatives 1 (c: R=CN ; d: R=p-C_6H_4CH_3, e: R=OCH_3) gave mainly, upon irradiation under the same conditions, isomerization about dhe double bond, high-molecular-weight products, small amount of phenanthrenes 5 and only traces of bicyclic structure 2.
