摘要: In a process for the preparation of epoxy group-containing alkoxy silanes by hydrosililation of a terminally unsaturated epoxy compound with a hydro-alkoxy silane using a platinum catalyst, the improvement comprising carrying out the hydrosililation in the presence of an alcohol. By this process formation of the internally sililated isomer can be suppressed and the desired terminally sililated poduct can be produced at an approximately 100% selectivity.
