    • A process for the preparation of trimethylsilyl cyanide comprising reacting trimethylsilyl chloride with an approximately equimolar amount of an alkali metal cyanide in the presence of a catalytic amount of a heavy metal cyanide and in the presence of an aprotic solvent with a boiling point above about 150.degree. C., at a temperature between about 130.degree. and 250.degree. C. Advantageously the reaction temperature is between about 160.degree. and 220.degree. C., the alkali metal cyanide is sodium cyanide or potassium cyanide, the heavy metal cyanide is copper(I) cyanide, copper(II) cyanide, zinc cyanide or a complex compound of one of them with an alkali metal cyanide and is employed in about 1 to 8 mol % relative to the alkali metal cyanide, and the mixture of aprotic solvent, heavy metal cyanide and alkali metal chloride remaining in the reaction vessel when the reaction has ended is used directly as the reaction medium for a further batch.
    • 一种制备三甲基甲硅烷基氰化物的方法,包括在催化量的重金属氰化物存在下,在沸点高于约150℃的非质子溶剂存在下,使三甲基甲硅烷基氯与近似等摩尔量的碱金属氰化物反应 有利地,反应温度在约160℃至220℃之间,碱金属氰化物为氰化钠或氰化钾,重金属氰化物为铜(I) 氰化物,氰化铜(II),氰化锌或其中一种与碱金属氰化物的配位化合物,相对于碱金属氰化物为约1〜8摩尔%,非质子溶剂,重金属氰化物 当反应结束时残留在反应容器中的碱金属氯化物直接用作另一批次的反应介质。
