Abstract

A process for preparing amphiphilic compounds having at least two hydrophilic and at least two hydrophobic groups by reacting an olefinic substrate having at least two double bonds with an organic hydroperoxide to form an oxirane ring, opening, the oxirane ring with an alcohol in the presence of a catalyst system comprising a molybdenum compound as a first catalyst component and a second catalyst component selected from the group consisting of boron trifluoride, alumina, 1,8-diazzabicyclo-(5.4.0)-undec-7-ene, 1,4-diazabicyclo-(2,2,2)-octane.
