Abstract

A single-stage method for producing &agr;-hydroxy ethers by oxidizing olefinic substrates with organic hydroperoxides and opening the resultant oxirane ring by means of monovalent or polyvalent alcohols wherein a molybdenum compound in combination with a compound selected from the group consisting of boron trifluoride, aluminum oxides, 1,8-diazabicyclo-[5.4.0]-undec-7-ene or 1,4-diazabicyclo-[2.2.2]-octane, and mixtures thereof is used as a catalyst system.
