1-Methyl-1-silabicyclo [2.2. 1] hept-2-ene was synthesized in 27% yield by chloramine-T oxidation of mixture of C-2/C-3 phenylselenide derivatives of 1-methyl-1-silabicyclo [2.2. 1] heptane. The phenylselenides in turn were produced in 8% yield by GifIII oxidation of 1- methyl-1-silabicyclo [2.2. 1] heptane. The 214 nm photolysis of the rigid 1-silanorbornene in MeOH or (CH3) 3COH resulted in [1, 3-C] migration to afford 3-alkoxy-3-methyl-3- ...
