The direct preparation of a kind of fluorinating reagent 1 [F‐TEDA‐N(SO 2 Ph) 2 ] was realized in high yield via the complexation of N ‐fluorobenzenesulfonimide (NFSI) with 1‐(chloromethyl)‐1,4‐diazabicyclo[2.2.2]octan‐1‐ium N′ , N′ ‐bis‐(benzenesulfonylimide) salt. In its fluorination to oxindoles, the fluorinating products 6 were afforded in moderate to high yields.
