Anwendungen
VerwendenHexamethyldisilane acts as a silylating reagent for allylic acetates, aryl halides and diketones. It is a source material for vapor deposition during silicon carbide growth. It is also used in electronic and semiconducter industries.
Darstellung
synthetischeHexamethyldisilane is produced by the reaction of methyl Grignard reagent with methylchlorodisilanes. This reaction is normally conducted in the presence of an ether such as diethyl ether, ethyl propyl ether, THF and the like.
