Reaction Steps

In a reactor wherein air was replaced by N2, 200.0 g of (1.2 mol) diethylphenyl phosphine and 400 mL of methanol were added and cooled to 15° C. by a ice-bath. 338.6 g (1.2 mol) of trifluoromethanesulfonimide was then added dropwise under strong stirring, and 202.0 g (2.2 mol) of dimethyl carbonate was also added after the reaction was complete. The reaction mixture was transferred to an autoclave, wherein air was removed prior to heating. After 2 hours of reaction at temperature of 180° C. and at pressure of from 1.2 MPa to 1.5 MPa, the crude product was obtained after distilling off the unreacted materials and solvent. 507.1 g of diethyl methyl phenyl phosphonium bis(trifluoromethanesulfonyl)amide was obtained after washing and drying at 60° C. and 0.1 kPa for 4 hours.
