[LMnX3]Y
(I)or a binuclear complex of the formula (II);
[LMn(μ
-X)3MnL](Y)n
(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;

Abstract
Processes are provided for the formation of an epoxyethyl ether or a glycidyl ether. In one embodiment, a process is provided for the manufacture of an epoxyethyl ether or glycidyl ether including 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 general formula (I): [LMnX3]Y (I), or a binuclear complex of the general formula (II): [LMn(μ-X)3MnL](Y)n (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, Y is a non-coordinating counter ion, and wherein the epoxidation is carried out at a pH in the range of from 1.0 to 6.0. The invention also relates to epoxyethyl ethers.
