Trifluoromethanesulfonic acid → HCID 86613024, compound

Participants

Reaction Steps

10.98 g (53.4 mmol) of 1,3-dimethyl-2-diethylaminoimidazolidinium chloride are dissolved in 70 cm3 of water, and 8.24 g (54.9 mmol) of trifluoromethanesulfonic acid are added at room temperature over the course of 5 min while the reaction mixture is stirred vigorously using a magnetic stirrer. The reaction mixture is stirred at room temperature for a further 5 min. All volatile components of the mixture are removed under reduced pressure. The residue is washed twice with 50 cm3 of diethyl ether and dried at 60° C. in an oil bath for three hours under a vacuum of 7.0 Pa, giving 16.7 g of a crystalline material (m.p. 67-68° C.). The yield of 1,3-dimethyl-2-diethyl-aminoimidazolidinium triflate is 97.9%, based on 1,3-dimethyl-2-diethyl-aminoimidazolidinium chloride.
