Photo-cycloaddition of Indene to Chlorofluoroethylenes and Some Reactions Concerning the Adducts

Article abstract of DOI:10.1246/bcsj.53.764

Benzophenone photo-sensitized addition of indene to chlorofluoroethylenes afforded 6,6,7,7-tetrahalogeno-2,3-benzobicyclo<3.2.0>hept-2-enes as corresponding cycloadducts.The structure of the cycloadducts obtained from unsymmetrical chlorofluoroethylenes shows that the addition reaction proceeds with good regioselectivity.Some reactions such as oxidation, reduction, dechlorination, and halogenation of the cycloadducts were also examined.
