Halogen/metal vs. hydrogen/metal exchange. General or specific site selectivity as exemplified in the camphene series

(Z)-(3,3-dimethylbicyclo[2.2.1]hept-2-ylidene)methyllithium can be readily generated by treatment of (Z)-3-bromomethylene-2,2-dimethylbicyclo[2.2.1]heptane with Me3CLi. At -75 Deg, the organometallic intermediate is configurationally stable and reacts with a variety of electrophiles under stereochem. retention. [on SciFinder (R)]
