  • Palladium-catalyzed enantioselective fluorination of tert-butoxycarbonyl lactone and lactam compounds. It can also be used for the electrophilic difluorination of dihalopyridine compounds under the action of butyl lithium, and the direct conversion of alcohols under the action of triphenylphosphine into bisbenzenesulfonimides. Stable and easy-to-handle crystalline material, easy to convert F+ into enolate and carbanion. A stable and mild fluorinating reagent for monofluorination of electron-rich aromatic compounds, enol silyl ethers, lithium enols, etc.; under the catalysis of small chiral organic molecules, NFSI can react with aldehydes, ketones, esters, etc. NFSI can perform electrophilic fluorination reaction on substrates such as aldehydes, ketones, esters and other substrates with high enantioselectivity under the catalysis of chiral metal complexes; As a fluorine reagent, it can be used for the addition reaction of double bonds; as a fluorine reagent, it can be used for the fluorination of aromatic compounds; used for the palladium-catalyzed enantioselective fluorination of tert-butoxycarbonyl lactone and lactam compounds; The electrophilic difluorination of dihalopyridine compounds under the action of butyllithium and the direct conversion of alcohols under the action of triphenylphosphine into bisbenzenesulfonimide compounds; mainly used as a fluorinating agent for electron-rich Monofluorination of aromatic compounds, enol silyl ethers, enol lithium salts, etc.
