    • It can be speculated that the solubility of the other Ar-BIAN compounds in acetic acid is largely due to the formation of hydrogen bonds between the acidic hydrogen and the imine nitrogens. Since the latter are strongly shielded in the bis-isopropyl derivative, this interaction is lacking or is very weak and the ligand precipitates. However, this explanation does not limit the validity of the concepts expressed above.

    • note
    • The largest deviations are observed at the extremes of the series, in accord with the following about the experimental error. Although the values calculated by integrating the acetate signals are slightly different from the ones calculated from the arylmethyl groups, the relative coordination strength order is unchanged, as is the ρ value (-3.48). The ratio determined from the arylmethyl groups is deemed to be more reliable because the corresponding signals are 2 times more intense and thus more precisely integrated.
