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-&lsqb;5.4.0&rsqb;-undec-7-ene or 1,4-diazabicyclo-&lsqb;2.2.2&rsqb;-octane, and mixtures thereof is used as a catalyst system.

Single-stage method for producing &agr;-hydroxy ethers by oxidizing C&equals;C unsaturated compounds with hydroperoxides

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.

Amphiphilic compounds with at least two hydrophilic and at least two hydrophobic groups on a di-,oligo- or polyene base

Single-stage method for producing &agr;-hydroxy ethers by oxidizing C&equals;C-unsaturated compounds with hydroperoxides

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.

Process for the preparation of vicinal diols and/or epoxides

An improved process for the production of carboxylic acids and dicarboxylic acids by the catalytic oxidation of olefins and vicinal diols by hydrogen peroxide is provided. The process employs a rhenium (VII) catalyst, and a solvent comprising a mixture of a carboxylic acid or anhydride having 2 or more carbon atoms and a high boiling cyclic or acyclic ether. Particularly suitable carboxylic acids or anhydrides include acetic acid, propionic acid and acetic anhydride. Particularly suitable high-boiling ethers include 1,4-dioxane and diglyme.
