Damrauer, Robert published the artcileSynthesis of fluorosilanes from chlorosilanes: the use of hexafluorosilicates, Name: Difluorodiphenylsilane, the publication is Organometallics (1988), 7(5), 1161-4, database is CAplus.
The conversion of chlorosilanes to fluorosilanes has been studied by using sodium and ammonium hexafluorosilicate. Of particular interest has been their efficiency in the conversion of highly hindered chlorosilanes like dimesityldichlorosilane and (Me3C)2SiCl2. (NH4)2SiF6 was superior reagent for these conversions, since its reactions are more easily worked up and give higher yields. In addition, (NH4)2SiF6 does not affect the Si-H, Si-Si, or Si-O-Si linkages as do many reagents which bring about chlorosilane to fluorosilane conversions.
Organometallics published new progress about 312-40-3. 312-40-3 belongs to catalysis-chemistry, auxiliary class Organic Silicones, name is Difluorodiphenylsilane, and the molecular formula is C12H10F2Si, Name: Difluorodiphenylsilane.
