The catalytic interaction of phenylchlorosilanes with methylchlorosilanes

Communication 1. Phenyltrichlorosilane and methylchlorosilanes

  • 30 Accesses

Conclusions

  1. 1.

    An investigation of the principles of the interaction of phenyltrichlorosilane with methylchlorosilanes under pressure at 250° in the presence of catalysts indicated that phenyltrichlorosilane reacts in all cases with replacement of a chlorine atom, while trimethylchlorosilane reacts with replacement of a methyl group.

  2. 2.

    The formation of dimethylphenylchlorosilane in the interaction of phenyltrichlorosilane and trimethylchlorosilane involves replacement of a chlorine atom of methylphenyldichlorosilane by a methyl group of dimethylchlorosilane.

  3. 3.

    Methyltrichlorosilahe does not react under these conditions with phenyltrichlorosilane, while the methyl group of dimethyldichlorosilane is replaced only at higher temperatures (300° and above).
