    • The rate of the initial protonation of 3 is significantly slower than any of the other models, but 3 is very rapidly protonated at the nitrogen atom. This means that the bridge protonation is occurring on an already charged species rather than the neutral compound.

    • 1H} NMR spectrum for 4 shows a single peak at δ = 21.79 ppm. On cooling to -60°C, this splits into broad signals at δ = 19.90 and 27.12 ppm and a sharp signal at δ = 28.34 ppm, demonstrating that more than one isomer is present in solution.
