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

N-Fluorobenzenesulfonimide (NFSI) (CAS: 133745-75-2), Versatile fluorinating reagent eji na fluorination nke aryls, enolates, carbanions, organolithiums, wdg.
N-Fluorobenzenesulfonimide bụ ihe a na-ejikarị electrophilic fluorinating agent na organic synthesis iji webata fluorine n'ime ụmụ irighiri ihe na-anọpụ iche.A na-ejikwa fluorinate nucleophilic substrates dị ka ụdị organometallic na-emeghachi omume na anions malonate.Enwere ike ijikọ NFSi site na mmeghachi omume nke benzenesulfonimide na fluorine.
N-Fluorobenzenesulfonimide bụ ihe ọhụrụ, kwụsiri ike ma dị nro fluorination reagent, nke nwere ike iwebata fluo rine atom n'ime carbonyl ortho ọnọdụ nke organic ụmụ irighiri, na ike ime monofluorination mmeghachi omume na electron-ọgaranya aromatic ogige, enol sila ne, ene Chemicalbook mmanya lithium nnu, wdg. Ebe nyocha nke ugbu a na-agụnye mmeghachi omume cyclization Nazarov nke ígwè ma ọ bụ cobalt na-eme ka ọ bụrụ mgbanaka nke ise, na asymmetric catalysis nke enantioselective α-fluorination.
N-Fluorobenzenesulfonimide fluorinates aromatics, enolates, azaenolates na carbanions na nnukwu mkpụrụ.A na-eji ya maka fluorination diastereoselective nke Li enolates nke chiral carboximides, maka ntụzịaka fluorination nke aromatics ortho-lithated na nyocha nke ndị na-ahụ maka fluorinating NF electrophilic.A na-eme fluorinations asymteric na ọnụnọ nke sistemu mmuta nke Pd-BINAP n'ime ụlọ okpomọkụ n'ime mmiri ionic.Ọ bụ reagent na-arụ ọrụ na palladium-catalyzed enantioselective fluorination nke t-butoxycarbonyl lactones na lactams.A na-ejikwa ya na electrophilic difluorination nke dihalopyridines na butyl lithium na ngbanwe nke mmanya na dibenzenesulfonamides na triphenylphosphine.
