Lithium bis((trifluoromethyl)sulfonyl)azanide → HCID 131730140, compound

Participants

Reaction Steps

Procedure 1c—A slight excess of lithium bis(trifluoromethylsulfonyl)imide dissolved in water was added to an aqueous solution of 1-butyl-1-methyl-azepanium iodide and stirred at room temperature for approximately 5 hours. The reaction mixture was transferred to a separating funnel and the heavy layer washed several times with water. The addition of a small amount of dichloromethane aided the separation of the aqueous and organic layer. The heavy organic layer was then evaporated to dryness leaving a pale yellow liquid, 1-butyl-1-methylazepanium bis(trifluoromethylsulfonyl)imide. δH (500.13 MHz, CDCl3) 3.42 (2H, m), 3.36 (2H, m), 3.22 (2H, m), 3.02 (3H, s), 1.88 (4H, m), 1.73 (6H, m), 1.40 (2H, sextet), 1.00 (3H, t). δC (125.76 MHz, CDCl3) 120 (q, CF3), 65.56, 64.84, 50.55, 27.46, 24.49, 21.80, 19.54, 13.37. ESI-MS: m/z=170 [M]+ (100). Calcd. for C11H24N: 170.1909; found: 170.1912, m/z=280 [M]− (100). Calcd. for C2F6NO4S2: 279.9173; found: 279.9163; Tg=−80° C.
