N-Fluorobenzenesulfonimide (NFSI) CAS 133745-75-2 Kuchena >98.0% (HPLC) Fluorinating Reagent

N-Fluorobenzenesulfonimide (NFSI) (CAS: 133745-75-2), Versatile fluorinating reagent inoshandiswa mu fluorination yearyls, enolates, carbanions, organolithiums, nezvimwewo.
N-Fluorobenzenesulfonimide inowanzoshandiswa electrophilic fluorinating agent mu organic synthesis kuunza fluorine mune neutral organic molecules.Inoshandiswawo kuita fluorinate nucleophilic substrates senge reactive organometallic marudzi uye malonate anions.NFSi inogona kugadzirwa nekuita kwebenzenesulfonimide ine fluorine.
N-Fluorobenzenesulfonimide itsva, yakagadzikana uye yakapfava fluorination reagent, inogona kuunza fluorine maatomu munzvimbo yecarbonyl ortho yema organic molecules, uye inogona kuita monofluorination reaction paelectron-rich anonhuwirira makomisheni, enol sila ne, ene Chemicalbook alcohol lithium salt, etc. Irizvino tsvakurudzo hotspots dzinosanganisira Nazarov cyclization reaction catalyzed nesimbi kana cobalt kuumba shanu-nhengo mhete, uye asymmetric catalysis enantioselective α-fluorination.
N-Fluorobenzenesulfonimide fluorinate aromatics, enolates, azaenolates uye carbanions mugoho guru.Inoshandiswa kune diastereoselective fluorination yeLi enolates ye chiral carboximides, inotungamirirwa fluorination ye ortho-lithiated aromatics uye yekuongorora kwe electrophilic NF fluorinating agents.Asymmteric fluorinations inoitwa pamberi pePd-BINAP catalyst system pane tembiricha yekamuri mune ionic mvura.Iyo reagent inoshandiswa mu palladium-catalyzed enantioselective fluorination ye t-butoxycarbonyl lactones uye lactams.Inoshandiswawo mu electrophilic difluorination ye dihalopyridines ine butyl lithium uye mukushandurwa kwakananga kwedoro kune dibenzenesulfonamides ine triphenylphosphine.
