Potassium methyltrifluoroborate, K[CH3BF3] (500 mg, 4.10 mmol), is suspended in trimethylsilyl cyanide (20 ml, 149.9 mmol). The reaction mixture is stirred at 50° C. for 2 days and subsequently at 80° C. for 24 hours. Excess trimethylsilyl cyanide and trimethylfluorosilane formed are distilled off and can be employed for further reactions. A slightly reddish solid is obtained.
