    • note
    • Since Selectfluor seems to decompose slowly in water, 3 equiv of reagent (not 2 equiv) was used when the reaction was performed in aqueous media just in case.

    • note
    • It is of particular interest to note that 3-fluorooxindoles 2 are solely produced in our system, while 3-fluoro-2-methoxyindoline is the product in the reaction of N-tosylindole with Selectfluor. See ref 17b.
