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. 320.3 g (1.14 mol) of trifluoromethanesulfonimide was then added dropwise under strong stirring, and 264.3 g (2.2 mol) of diethyl carbonate was also added after 1 hour of reaction. 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 1.4 MPa to 1.5 MPa, the crude product was obtained after distilling off the unreacted materials and solvent. 599.5 g of ethyl triphenyl phosphonium bis(trifluoromethyl sulfonyl) amide was obtained after washing and drying at 60° C. and 0.1 kPa for 4 hours.
