実験手順

93 g (0.5 mol) of pivalic acid anhydride and 1 g of sodium cyanide are initially introduced and 49.5 g (0.5 mol) of trimethylsilyl cyanide are added dropwise. The reaction mixture is worked up by distillation. Yield: 56 g of pivaloyl cyanide (=98.9% of theory). Boiling point: 121°-125° C. In addition, pivalic acid-trimethylsilyl ester is obtained in a corresponding amount (98% of theory).
