Participants

Reactant 2

HCID 82115Trimethylsilyl cyanide

HCID 23692566Potassium Trifluoro(methyl)borate

Product 2

HCID 9869Fluorotrimethylsilane

HCID 82115Trimethylsilyl cyanide

Conditions

Temperature: 80 °C

Procedure

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.
