Sliver bis(trifluoromethane sulfonimide) synthesis

Yield:-

Reaction Conditions:

in isopropyl alcohol for 0.5 h;

Steps:

1 Route B:
A mixture of 0.5 mol N,N,N′,N′-tetramethylethylenediamine (58.1 g) and 0.1 mol of 2-ethylhexyl bromide (19.3 g) was refluxed for 12 h. Unreacted tetramethylethylenediamine was removed under vacuum, and the yield of 2-ethylhexyltetramethylethylenediamine was 100%. Next, a solution of 0.1 mol of silver bis(trifluoromethane)sulfonamide was made by vigorously stirring a suspension of 0.05 mol silver (I) oxide (11.57 g) and 0.1 mol bis(trifluoromethane)sulfonamide (28.1 g) in isopropanol. After 0.5 h of reaction, the solution of silver bis(trifluoromethane)sulfonamide was added dropwise to a solution of 0.1 mol of 2-ethylhexyltetramethylethylenediamine (30.9 g) in isopropanol with continuous stirring. The resulting silver bromide was removed by a sequence of three centrifugations of the reaction mixture and decantation. Isopropanol was then removed by vacuum.
