Epoxyorganoalkoxysilanes are made by reacting an olefin epoxide with an hydridoalkoxysilane in the presence of RhCl(di-tert-butylsulfide)<SUB>2 </SUB>catalyst. The reaction is free of the presence of a stabilizing agent, it is carried out at a temperature in the range of 65-95° C., and the olefin epoxide is present in the reaction in a molar excess of 5-25 percent over the stoichiometric amount necessary to react with the hydridoalkoxysilane. Preferably, the reaction temperature is in the range of 70-75° C., and the olefin epoxide is present in the reaction in a molar excess of about 10 percent over the stoichiometric amount necessary to react with the hydridoalkoxysilane.
