The 1-substituted norborn-2-enes 11–13 and 18 react with electrophiles under kinetic control preferentially in 2-position. The regioselectivity in oxymercuration is higher than in hydroboration and reaction with aqueous palladium chloride.

Reductive elimination at 1,2exo-diiodonorbornane (6) was induced by Collman's reagent. Surprisingly, 1,2endo-diiodonorbornane (9) and 1-iodo-2endo-trifluoromethylsulfonyloxy-norbornane (10b) lead only to reactions of the substituent in 2-position. Mechanistic aspects are related to the reactions of monosubstituted iodonorbornanes with Collman's reagent.
