    • It is interesting that, on the basis of IR studies, it was shown that the MeSO group acts as a net resonance donor (N. C. Coutress, T. B. Grindley, A. R. Katritsky, R. D. Topsom, J. Chem. Soc. Perkin II 1974, 263); however, the above interpretation was found inconsistent with the NMR findings of Buchanan et al. (G. W. Buchanan, C. Rayes-Zamora, D. E. Clarke, Can. J. Chem. 1974, 52, 3895).

    • It should be noted that the structure of Scheme 2 (left) is slightly different from the most stable conformation of phenyl methyl sulfoxide found by Benassi (R. Benassi, U. Folli, D. Iarossi, A. Mucci, L. Schenetti, F. Taddei, J. Chem. Soc. Perkin Trans 2 1989, 517; R. Benassi, A. Mucci, L. Schenetti, F. Taddei, J. Mol. Struct. 1989, 184, 281), in which the S=O bond is almost coplanar with the phenyl ring.

    • One could argue that 1-12, 15, and 16 should be considered as intrinsically dissymmetric chromophores, requiring an MO treatment. We intend to begin such a type of analysis.
