NFSI vs Selectfluor, which one to choose?
May 11，2026
Selectfluor is usually more reactive than NFSI and is suitable for substrates that are difficult to react. On the other hand, due to its greater mildness, NFSI (N-Fluorobenzenesulfonimide) can better control selectivity and reduce oxidative side reactions.
