Abstract
Cyclic or linear siloxanes are obtained by hydrolysing monoaryl-dihalosilanes and condensing the resulting product to give a siloxane having a hydrogen atom directly attached to silicon.ALSO:A monoaryl-dihalosilane is prepared by reacting an aryl magnesium halide with approximately its molecular equivalent or more of a trihalosilane in the presence of an ether, e.g. at a temperature between 0 DEG and -70 DEG C. Suitable trihalosilanes are trichloro-tribromo- and trifluoro-silane. Suitable aryl magnesium halides are phenyl magnesium bromide and chloride, p-methylphenyl magnesium bromide and chloride, p-methylphenyl magnesium bromide and chloride, o, m, and p-biphenyl- and alpha- and beta-naphthyl mag-nesium chlorides. The ether employed may be any of those used in Grignard reactions, e.g. dimethyl-, diethyl-, dipropyl- and dibutyl-ether. In examples, the following compounds are prepared: phenyl-, mono-alpha-naphthyl-, p-methylphenyl-, and p-chlorophenyl-dichlorosilane. Similarly monophenyl- and alpha- or beta-naphthyl-dibromosilane, o, m or p-biphenyl-dichlorosilane and p-methylphenyl-difluorosilane may be prepared. The products may be hydrolysed and condensed.
