In the process for the preparation of vinylsilanes by reacting acetylenic hydrocarbons with silanes which have at least one silicon-bonded hydrogen atom in the liquid phase in the presence of a catalyst, the silane is added to the liquid phase. In particular, the reaction is carried out at superatmospheric pressure, and the spent acetylenic hydrocarbon is replenished during the reaction while maintaining a pressure which is constant during the entire reaction.
