Thexyl (C1-C4)alkyl dialkoxy silanes; methods of preparation; and uses thereof.

摘要

Thexyl (C1-C4) alkyl dialkoxy silanes are a class of novel organosilicon compounds, including thexyl methyl dimethoxy silane and thexyl n-butyl dimethoxy silane, and can be synthesized by several different routes. For example, thexyl methyl dimethoxy silane is prepared starting from methyl phenyl chlorosilane which is subjected to the hydrosilation reaction with 2,3-dimethyl-2-butene to introduce a thexyl group and the compound is converted by the reaction with hydrogen chloride into thexyl methyl dichlorosilane which is methoxylated by the reaction with methyl alcohol. Uses include water-repellant agents and additives for olefin polymerisation catalysts.
