with sodium iodide in acetone, although they coulc be made by the action of phosphoric acid and potassium iodide on the (methoxymethyl)disilanes, with yields and purities being much lower. 1,2-Bis(chloromethyl)tetramethyldisilane was prepared pure, but in very low yield, by the action of diazomethane on sym-dimethyltetrachlorodisilane followed by methylation of the remaining siliconchlorine bonds.
描述了一种非常方便的方法来制备
溴甲基取代的有机乙
硅烷,该方法涉及使相应的(甲氧基甲基)乙
硅烷与三苯基二
溴phoshporane反应。(
碘甲基)乙
硅烷最好通过在
丙酮中用
碘化钠处理(
溴甲基)乙
硅烷来制备,尽管它们是由
磷酸和
碘化钾作用在(甲氧基甲基)乙
硅烷上制得的,但收率和纯度要低得多。通过
重氮甲烷对对称的-二甲基四
氯乙
硅烷的作用,然后剩余的
硅氯键的甲基化,以纯净的方式制备1,2-双(
氯甲基)四甲基乙
硅烷,但收率非常低。
