Abstract
Polymeric compounds are obtained by polymerizing allyl silicon fluorides. Diallyldifluoro-and triallylmonofluoro-silanes are mentioned. A resin is obtained by hydrolysing with aqueous sodium carbonate and heating, the product obtained by passing silican tetrafluoride into ethereol ethyl magnesium bromide-probably diethylsilicon difluoride.ALSO:Organo-silicon fluorides of the formula RxSiF(4-x), wherein R represents an alkyl, alkenyl, aryl or arlakyl group directly attached to the silicon atom and x is 1 or 2, are prepared by the reaction of RMgX, wherein R and X have the above significance, with a proportion of silicon tetrafluoride sufficient to produce said organo silicon fluorides in which this result is achieved by continuously adding the Grignard reagent to ether or other inert liquid medium into which silicon tetrafluoride is continuously passed, e.g. the rate of addition of silicon tetrafluoride may be such that the reaction mixture is saturated with silicon tetrafluoride. The products may be separated by distillation. In the examples, silicon tetrafluoride is reacted with phenyl magnesium bromide, ethyl magnesium bromide, benzyl magnesium chloride and allyl magnesium bromide. In the latter case some triallylmonofluorosilane is formed. Diphenylsilicon dihydroxide is obtained by hydrolysing diphenylsilicon difluoride with aqueous sodium hydroxide. Dibenzylsilicon diol and anhydrobisdibenzyl silicone are obtained by the alkaline hydrolysis of dibenzylsilicon difluoride.
