| 摘要 |
The invention relates to a method for producing neopentasilanes of the general formula (1) Si(SiR3)4 (1), wherein silicon compounds of the general formula (2) R3Si- (SiR2-)xSiR3 (2), where R is selected from Cl, Br, and I, and x is a non-negative whole number up to 5, are converted in the presence of catalytically active compounds (K), wherein the separating of the tetrahalogen silane formed thereby takes place by distilling out in the presence of a compound (L) that is liquid at room temperature having a higher boiling point than the released tetrahalogen silane.
