Abstract:
1. A process for the manufacture of an epoxyethyl ether or a glycidyl ether, comprising: reacting a vinyl ether or an allyl ether with an oxidant in the presence of a water-soluble manganese complex in an aqueous reaction medium, wherein the water-soluble manganese complex comprises an oxidation catalyst, characterized in that the water-soluble manganese complex is a mononuclear complex of the formula (I): or a binuclear complex of the formula (II): wherein Mn is a manganese; L or each L independently is a polydentate ligand, each X independently is a coordinating species and each μ-X independently is a bridging coordinating species, wherein Y is an anion, n is 1 or 2, and wherein the reaction is performed at a pH in the range of from 1.0 to 6.0 and the molar ratio of the vinyl ether or the allyl ether to the oxidant is from an excess vinyl ether or the allyl ether to 12:1, wherein each polydentate ligand is independently selected from acyclic compounds having at least 7 atoms in the backbone or cyclic compounds having at least 9 atoms in the ring, wherein each polydentate ligand having 3 nitrogen atoms with the nitrogen atoms separated by at least two carbon atoms, and wherein the oxidant comprises hydrogen peroxide, dilute hydrogen peroxide, or is selected from group consisting of organic peroxides, peracids, and combinations thereof.
