Bicyclo[3,2,1]octa-2,6-diene (1) has been lithiated directly with t-butyllithium/TMEDA at low temperature. After quenching with tri-methyltin chloride essentially two stannyl derivatives of 1 were obtained. The stannyl group did not bind to the allylic carbon of 1 as expected but to C-6 and C-7. This has been shown by means of elemental analysis, mass spectroscopy as well as  1 H,  13 C and  119  Sn NMR spectroscopy.
