Substituted alkyhnethylenecyclohexanes were hydrogenated over several transition metal catalysts. The ratios of the epimeric products were almost unity over freshly prepared Raney Ni but the axial Me counterparts were favoured over aged catalyst. The axial Me products were also preferred on Pt or Rh

## Abstract The 1βsubstituted norbornβ2βenes **11β13** and **18** react with electrophiles under kinetic control preferentially in 2βposition. The regioselectivity in oxymercuration is higher than in hydroboration and reaction with aqueous palladium chloride.
