Uses: NFSI is a new, stable and mild fluorination reagent, which can introduce fluorine atoms in the carbonyl o-site of organic molecules, and can monofluorinate electron-rich aromatic compounds, enolsilthers, enollithium salts, etc. Current research focuses on the formation of five-membered ring Nazarov cyclization catalyzed by iron or cobalt, asymmetric catalysis of enantioselective α-fluorination.
