Abstract

The present invention provides a process for the preparation of vicinal diols and/or epoxides by the oxidation of olefinically-unsaturated compounds with the use of an inorganic heptavalent rhenium compound as catalyst and of hydrogen peroxide as oxidation agent, wherein the reaction is carried out in a solvent selected from the group consisting of organic phosphoric acid esters and ethers with a boiling point above 50.degree. C. under atmospheric conditions.
