    • Disulfide can be easily removed by washing with diethyl ether. Compound 2 was obtained in 33% yield through addition of a stoichimetric amount of p-TsOH, whereas no thiol at all was isolated with methanolic HCl.

    • On stirring (1R)-N,N-dimethyl-1-phenylethylamine with methyl iodide at room temperature in THF, precipitation occurred rapidly. The solid product was identified as the ammonium salt and was isolated in quantitative yield after a reaction time of 2 h.

    • In contrast, oxidation with the more classical benzaldehyde-derived oxaziridine, namely, (±)-trans-2-(phenylsulfonyl)-3-phenyloxaziridine, gave a complex mixture in which sulfoxides 3a and 4a could be detected (yield < 40%). Among the side products, 1-methylsulfanyl-2-vinyibenzene was produced in 28% yield, with spectral data in agreement with those reported: Bianchini, C.; Frediani, P.; Herrera, V.; Jiménez, M. V.; Meli, A.; Rincón, L.; Sánchez-Delgado, R.; Vizza, F. J. Am. Chem. Soc. 1995, 117, 4333-4346. The formation of this styrene derivative can be interpreted in terms of a competitive oxidation on nitrogen followed by Cope elimination and illustrates the difference of oxidizing power of the two oxaziridines.

    • No X-ray crystallographic structural data for sulfenate salts has been reported in the literature. However, we believe that lithium is coordinated to oxygen rather than to sulfur, on the basis of the accepted concepts of hard and soft acids and bases: Pearson, R. G.
