    摘要： Process for the preparation of bisepoxides, wherein a conjugated diene of the formula I where R1 is selected from hydrogen and C1-C12-alkyl, unsubstituted or substituted by one or more S—H or O—H groups, is reacted in the presence of a catalyst which is obtainable by bringing at least one manganese compound selected from A2MnX4, AMnX3, MnY, MnX2 and MnX3 into contact with at least one ligand L of the formula II where X are identical or different and are selected from monovalent anions, Y is a divalent anion, A is selected from alkali metal and ammonium, which may be alkylated, R2 are identical or different and are selected from C1-C20-alkyl, and at least one coligand which is derived from monocarboxylic acids, dibasic or polybasic carboxylic acids or diamines, with at least one peroxide, up to 4 equivalents of peroxide being used per equivalent of C—C double bond.
