PROBLEM TO BE SOLVED: To provide a method for producing a mercaptorganyl(alkoxysilane) in high conversion through reductively splitting the corresponding bis(alkoxysilylorganyl) polysulfide without using any further antipoisening reagent such as water, an alcohol or hydrogen sulfide for a necessary metal catalyst. SOLUTION: The method for producing the mercaptorganyl(alkoxysilane) comprises hydrogenating the corresponding bis(alkoxysilylorganyl) polysulfide in the presence of a metal catalyst in a solvent at a temperature lower than 190°C under a pressure lower than 100 bar without addition of water, an alcohol or hydrogen sulfide.
