N-Fluorobenzenesulfonimide (NFSI) CAS 133745-75-2 daahirnimo>98.0% (HPLC)

N-Fluorobenzenesulfonimide (NFSI) (CAS: 133745-75-2), reagent fluorinating Versatile loo isticmaalo fluorination of aryls, enolates, carbanions, organolithiums, iwm.
N-Fluorobenzenesulfonimide waa wakiilka fluorinating electrophilic oo si caadi ah loo isticmaalo si loogu soo bandhigo fluorine molecules organic dhexdhexaad ah.Waxa kale oo loo isticmaalaa in lagu buufiyo substrates nucleophilic sida noocyada organometallic fal-celinta iyo anions malonate.NFSi waxaa lagu soo saari karaa falcelinta benzenesulfonimide ee leh fluorine.
N-Fluorobenzenesulfonimide waa cusub, xasiloon oo khafiif ah reagent fluorination, kaas oo soo bandhigi kara atamka fluo rine booska carbonyl ortho ee molecules organic, oo samayn kara falcelin monofluorination on xeryahooda udgoon electron-hodan, enol sila ne, ene Chemicalbook khamriga lithium cusbo, iwm. Goobaha cilmi-baarista ee hadda jira waxaa ka mid ah falcelinta baaskiilka ee Nazarov oo ay katay birta ama cobalt si ay u sameeyaan giraan shan xubnood ah, iyo catalysis asymmetric of enantioselective α-fluorination.
N-Fluorobenzenesulfonimide fluorinates aromatics, enolates, azaenolates iyo carbanions ee wax soo saarka sare.Waxaa loo isticmaalaa fluorination diastereoselective of Li enolates of chiral karboximides, loogu talagalay fluorination-ka ee aromatics ortho-lithated iyo dib u eegis ee wakiilada fluorinating NF electrophilic.Floorinnada asymteric waxaa lagu sameeyaa joogitaanka nidaamka kicinta Pd-BINAP heerkulka qolka ee dareeraha ionic.Waa reagent ka shaqeeya palladium-catalyzed enantioselective fluorination of t-butoxycarbonyl lactones iyo lactams.Waxa kale oo loo isticmaalaa difluorination electrophilic ee dihalopyridines leh butyl lithium iyo beddelka tooska ah ee alkolada si dibenzenesulfonamides leh triphenylphosphine.
