Triethyloxonium tetrafluoroborate → HCID 178465536, compound

Participants

Reaction Steps

3.20 g (16.83 mmol) of triethyloxonium tetrafluoroborate are added to a solution of 3.73 g (16.64 mmol) of N,N,N′,N′-tetramethyl-N″-ethylguanidinium bromide in 10 ml of dry dichloromethane. The reaction mixture is stirred at room temperature for 30 minutes. All volatile products are subsequently removed over the course of 30 minutes in a vacuum of 13.3 Pa and at 80° C. (oil-bath temperature), giving 3.84 g of N,N,N′,N′-tetramethyl-N″-ethylguanidinium tetrafluoroborate. The yield is approximately quantitative.
