    • 1H NMR spectra in which aromatic protons of the iodobenzene moiety were observed together with the disappearance of those of the sulfonamide function and the upfield shift of the alkane protons. For example, for the iminoiodinane derived from sulfonamide 9c: δ 1.26 (m, 2H), 1.76 (m, 2H), 2.00 (m, 2H), 4.95 (m, 2H), 5.64 (m, 1H), 7.39 (m, 2H), 7.54 (m, 1H), 7.96 (d, 1H).

    • note
    • The iodinanes were used as soon as they were isolated in order to optimize the yield of the aziridination. However, they could be stored at 4 °C under argon for several days. Their stability is therefore comparable to that of PhINTs or PhINSes.

    • To the best of our knowledge, there is only one example of the preparative use of such a Cu-catalyzed C-H insertion: Overman, L. E.; Tomasi, A. L. J. Am. Chem. Soc. 1998, 120, 4039. In other cases, such compounds were isolated as minor byproducts. For example, see: (a) ref 15. (b) Albone, D. P.; Aujla, P. S.; Taylor, P. C.; Challenger, S., Derrick, A. M. J. Org. Chem. 1998, 63, 9569.
