    • Distinguishing syn from anti addition is trivial, since the cyclobutene ring in product 4x is unsubstituted only for syn addition, resulting in a very characteristic AB quartet. Anti addition would also remove characteristic AB quartets in 2x and 3x (as is seen for 1b).

    • These calculations were run by locking the internal carbon of the double bond 3 Å from the benzene carbon bearing the tether and then computing energies for various angles of rotation around the benzene-oxygen bond.
