    • A method for forming a dialkyldichlorosilane, comprising reacting elemental silicon with an alkyl chloride using copper as a catalyst together with promoters zinc, tin, and a special promoter. The special promoter is silver, a silver compound, gold, a gold compound, or combinations thereof. The alkyl may be methyl such that the dialkyldichlorosilane is dimethyldichlorosilane and the alkyl chloride is methyl chloride. The reacting generates the dialkyldichlorosilane in accordance with a first selectivity for the dialkyldichlorosilane that exceeds a second selectivity for the dialkyldichlorosilane. The second selectivity is a selectivity for the dialkyldichlorosilane that would have existed had the special promoter been absent.
    • 一种形成二烷基二氯硅烷的方法,包括使用铜作为催化剂与促进剂锌,锡和特殊的促进剂一起使元素硅与烷基氯反应。 特殊促进剂是银,银化合物,金,金化合物或其组合。 烷基可以是甲基,使得二烷基二氯硅烷是二甲基二氯硅烷,并且烷基氯是甲基氯。 该反应根据对二烷基二氯硅烷的第二选择性的二烷基二氯硅烷的第一选择性产生二烷基二氯硅烷。 第二选择性是对于二烷基二氯硅烷的选择性,如果没有特殊促进剂,那么它将存在。
