Properties of N-Fluorobenzenesulfonimide CAS 133745-75-2
NFSI is white solid appearance and a new, stable and mild fluorinating reagent. It can introduce fluorine atoms at the ortho position of the carbonyl group in organic molecules, and can perform monofluorination reactions on electron-rich aromatic compounds, enol silyl ethers, and olefin Chemicalbook alkoxide lithium salts. Current research hotspots are the Nazarov cyclization reaction to form a five-membered ring under the catalysis of iron or cobalt, and the asymmetric catalysis of enantioselective α-fluorination.
