Reaction Steps

In a reactor wherein air was replaced by N2, 300.0 g of (1.1 mol) triphenyl phosphine and 500 mL of methanol were added and cooled to 10° C. by a ice-bath. 321.8 g (1.1 mol) of trifluoromethanesulfonimide was then added dropwise under strong stirring, and 202.0 g (2.2 mol) of dimethyl carbonate was also added afterwards. After one hour of reaction and mixing, the reaction mixture was transferred to an autoclave, wherein air was removed prior to heating. After 4 hours of reaction at temperature of 160° C. and at pressure of from 1.4 MPa to 1.5 MPa, the crude product was obtained after distilling off the unreacted materials and solvent. 584.8 g of methyl triphenyl phosphonium bis(trifluoromethanesulfonyl)amide was obtained after recrystallization and drying at 60° C. and 0.1 kPa for 4 hours.
