Method for the preparation of polysulfane silanes by means of phase transfer catalysis |
| abstract |
Process for the preparation of polysulphane silanes by means of phase transfer catalysis The invention relates to a process for the preparation of polysulphane silanes of the formula I (R 1 ) 3-m R 2 m Si-R 3 -S x -R 3 -SiR 2 m (OR 1 ) 3-m I by reacting at least one silane of the formula II (R 1 ) 3-m R 2 m Si-R 3 -Hal II with M (SH) y and / or M z S and sulfur, in the presence of a phase transfer catalyst of the formula at least one carrier steam distillation and / or ozone treatment being carried out during or after the reaction. |
