摘要

Photolysis of α, β-diacetoxystilbene (1) adsorbed onto a Fe3+-doped sepiolite (Fe-Sp) leads to benzoic acid (3), 9, 10-diacetoxyphenanthrene (5), diphenic anhydride (6), and benzil (7). While compounds 3, 5 and 6 are also observed in the direct irradiation of 1 in hexane solution, diketone 7 is formed under electron transfer conditions using 2, 4, 6- triphenylpyrylium tetrafluoroborate as photosensitizer. These results strongly suggest that ...
