Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The direct preparation of a kind of fluorinating reagent <bold>1</bold> [F‐TEDA‐N(SO₂Ph)₂] was realized in high yield via the complexation of <italic>N</italic>‐fluorobenzenesulfonimide (NFSI) with 1‐(chloromethyl)‐1, 4‐diazabicyclo[2.2.2]octan‐1‐ium <italic>N′</italic>, <italic>N′</italic>‐bis‐(benzenesulfonylimide) salt. In its fluorination to oxindoles, the fluorinating products <bold>6</bold> were afforded in moderate to high yields.</p> </abstract>
