Sažetak
The intermediates, 3a, 9-dihydro-4, 9-methano-4H-benzo[4, 5]cyclohepta[1, 2-b]furan (3a), and 5b, 11-dihydro-6, 11-methano-6H-benzo[4, 5]cyclohepta[1, 2-b]benzo[d]furan (3b), formed upon irradiation of 2-[2-(2-vinylphenyl)ethenyl]furan (1a) and 2-[2-(2-vinylphenyl)ethenyl]benzo[b]furan (1b), respectively, are determined and spectroscopycally characterised. Whereas only the intermediate (3b) reacts photochemically with methanol to give the regioselective adduct (6b), both intermediates are trapped by molecular oxygen giving hydroperoxides (7a, b), hydroxy- (8a, b), and keto derivatives (9a, b).
