- 中文摘要: The irradiation of 2,3-bis(tert-butylsulfonyl) norbornadiene and 2-(tert-butylsulfonyl)norbornadiene yielded the expected quadricyclane derivatives as stable molecules. The irradiation of 2,3-bis(tert-butylsulfonyl) bicyclo [ 2.2.2 ] octa-2,5-diene ( 7), 2,3-bis(tert- butylsulfonyl)-exo-7,8-epoxybicyclo [ 2.2.2 ] -octa-2,5- diene (8) and 8,9-bis(tert-butylsulfonyl)-4-anti-phenyl-3,5- dioxa-exo-tricyclo [ 5.2.2.0/sup 2.6/ ] undeca-8,10-diene(9a) and its syn-isomer (9b) yielded the corresponding tetracyclic and pentacyclic systems, respectively. The photoproducts of (8) and (9) reverted to the starting products slowly at room temperature. The half-life of the photoproduct of (7) was determined to be 34 mins at 50.degree.C. Compound (9a) reacted with n-BuLi to yield the unexpected desulfonylation product (27a).
