The insertions of norbornene, bicyclo[2.2.1]hept-5-ene- endo -2-carboxylic acid ethyl ester, bicyclo[2.2.1]hept-5-ene- exo -2-carboxylic acid ethyl ester, and bicyclo[2.2.1]hept-5-enyl- endo -2-methyl acetate into the palladium−methyl bond of (η 4 -cycloocta-1,5-diene)chloromethylpalladium(II) were found to proceed at similar rates, with the product in every case being derived from insertion through the exo face.
