Synthesis method
N-Fluorobenzene sulfonimide tuaj yeem npaj tau los ntawm kev siv benzenesulfonic acid ua raw khoom thiab reacting nrog fluorine reagent nyob rau hauv qhov tsim nyog cov tshuaj tiv thaiv.
Kev siv
Fluorinating tus neeg sawv cev: N - Fluorobenzenesulfonimide (NFSI) ua tus neeg sawv cev fluorinating tuaj yeem ua cov tshuaj tiv thaiv monofluorination ntawm electron - nplua nuj aromatic compounds, enol silyl ethers, enol lithium ntsev, thiab lwm yam. Tsis tas li ntawd, nws muaj peev xwm hnov mob nrog qee cov tebchaw nrog active methylene pawg los ua ke mono - lossis di. - fluorinated compounds.
Asymmetric Fluorination Raj: Cov tebchaw nrog nquag - hydrogen yuav siv tau ua cov precursors rau cov tshuaj asymmetric fluorination. Cov no suav nrog - Ketoesesters, - Carbonhosphosphonates, - Ketoamides, - Cyananyesters, HydroxyNtive Esters lossis Thawj Aldehyde Esters.
Tandem fluorination cov tshuaj tiv thaiv: N - fluorobenesulfonimide (NFSI) raws li Electrophilic fluorinating tus neeg sawv cev tau ua tiav rau Tandem fluorination kev tawm tsam. Piv txwv li, siv chiral phosphinamide li cov neeg tshawb nrhiav tau ua tiav tooj liab - catalyzed 1, {}}}}}}}}}} tandem cov tshuaj tiv thaiv / fluidation.
