Beschreibung
Zusammenfassung:	The present invention provides a method for preparing alkenylsilanes whereby a gaseous mixture consisting essentially of an acetylenic hydrocarbon and a silane containing a silicon-bonded hydrogen atom is directed into contact with a reaction medium in the form of a relatively thin moving liquid layer or film. The reaction medium comprises a solubilized hydrosilylation catalyst and the alkenylsilane produced as a product of the reaction. The reaction medium can optionally include an organic liquid that is a solvent for the catalyst, alkenylsilane and acetylenic hydrocarbon reactant.
