| Abstract: | Upon irradiation of a benzene-d6 solution of 1,2,2,5-tetrakisdi-tert-butyl(methyl)silyl]-4,7-diaryl- 1,2,5-trisilabicyclo-3.2.0]hepta-3,6-diene 1a: aryl = phenyl, b: aryl = 3,5-bis-(trimethylsilyl)phenyl], 1,4,7,7-tetrakisdi-tert-butyl-(methyl)silyl]-2,5-diaryl-1,4,7- trisilabicyclo2.2.1]hepta-2,5-diene (2a,b) was formed via skeletal rearrangement. |
