A process for producing compounds of the formula (CH.sub.3).sub.3 SiORLi, wherein R is selected from alkyl groups containing 2 to 10 carbon atoms and aryl groups containing 6 to 10 carbon atoms, by reacting, optionally in the presence of a catalyst, in an inert atmosphere, a haloalcohol of the formula HORX, wherein R is selected from alkyl groups containing 2 to 10 carbon atoms and aryl groups containing 6 to 10 carbon atoms and X is selected from chlorine or bromine, is reacted with neat hexamethyldisilazane at a temperature between 20.degree. C. and 200.degree. C., optionally in the presence of a catalyst, after which the resulting product, a trimethylsilyloxyalkylhalide compound, is reacted at a temperature between 50.degree. C. and 160.degree. C., with powdered lithium metal, in an inert hydrocarbon medium, to produce the (CH.sub.3).sub.3 SiORLi compound.
一种制备化合物(CH.sub.3).sub.3 SiORLi的方法,其中R选择含有2到10个碳原子的烷基或含有6到10个碳原子的芳基,通过在惰性气氛下反应式为HORX的卤代醇,其中R选择含有2到10个碳原子的烷基或含有6到10个碳原子的芳基,X选择氯或溴,可选地在催化剂的存在下,在20℃到200℃的温度下与纯六甲基二硅氨反应,随后在惰性烃介质中,以50℃到160℃的温度,与粉末状锂金属反应,产生(CH.sub.3).sub.3 SiORLi化合物。
