Conditions

Temperature
70 °C

Procedure

B(OCH3)3 (20.0 g, 0.19 mol) and KCN (12.5 g, 0.19 mol) were dissolved in TMSCN (66.8 g, 0.67 mol) and heated at a reflux temperature of 70° C. under protective gas for 18 hours. After cooling, all volatile components (unreacted TMSCN, formed TMSOMe) were distilled off to give powdery K[B(CN)3(OCH3)] in a yield of 27.8 g (92%).
