摘要：

The triplet sensitized rearrangement of benzonorbornadiene (1,4-dihydro-l,4-methanonaphthalene) has been studied in detail. Through labeling experiments, evidence is obtained for an intermediate diradical which resembles a partially closed quadricyclane ring. The quantum yield for the reaction is 0.5 with the T1 state of benzonorbornadiene estimated to be 70 kcal. No fluorescence was detected from benzonorbornadiene and evidence is presented which points to a facile rearrangement during direct irradiation which differs from the triplet-state reaction. © 1969, American Chemical Society.
