Trimethylsilyl Pseudohalide Adducts of GaCl3 and B(C6F5)3

Me3Si?X (X=CN, N3, OCN, and SCN) was treated with the Lewis acids GaCl3 and B(C6F5)3 in toluene yielding the desired adducts Me3Si?X→GaCl3 and Me3Si?X→B(C6F5)3. All synthesized adducts were isolated and completely characterized including single crystal structure elucidations. The different structures, thermodynamics of formation and charge transfer effects are discussed on the basis of experimental and theoretical data.

A Convenient Method for the Synthesis of Alkylsilyl Cyanides Using Potassium or Sodium Cyanide Impregnated on Amberlite XAD Resin

Potassium and sodium cyanide impregnated on Amberlite XAD resin were found to be effective for converting alkylsilyl chloride to the corresponding alkylsilyl cyanide under mild conditions.

Process for preparing dimethylsilyl dicyanide

A process for preparing dimethylsilyl dicyanide comprising reacting trimethylsilyl cyanide with dimethylsilyl dichloride. Advantageously the trimethylsilyl chloride formed as a by-product in the course of the reaction is continuously removed from the reaction, the trimethylsilyl cyanide starting material is produced by reacting trimethylsilyl chloride with an alkali metal cyanide, and the by-product trimethylsilyl chloride of the principal reaction is recycled to the preparation of trimethylsilyl cyanide.
