    • Reproducibilities are good; the experimentally determined error limit of the S factor is ± 5%.

    • note
    • Analogous experiments with pure -o-nitrophenylethylamine (5) as the inhibitor led to a de value of 51% and an S factor of 0.55. With pure (S)-p-nitrophenylethylamine as the inhibitor the de value was 62% and the S factor was 0.56. We conclude that use of the more readily available mixture instead of the pure materials is entirely justified and allows direct comparison with the data given in ref. [3].

    • note
    • In this experiment we used only o-nitrophenylethylamine instead of the 1:1 mixture of o,p isomers for reasons of simplicity.

    • note
    • The dissolution temperatures differ somewhat, owing to the high concentrations in this experiment (1.6M); the experimentally determined error limit is ± 0.7 °C.
