    • 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.
    • 二环氧化物的制备方法,其中式I的共轭二烯,其中R1选自氢和未被取代或被一个或多个SH或OH基取代的C 1 -C 12 - 烷基,在催化剂存在下反应, 可以通过使至少一种选自A2MnX4,AMnX3,MnY,MnX2和MnX3的锰化合物与至少一种式II的配位体L进行接触,其中X是相同或不同的并且选自一价阴离子,Y是二价阴离子, A选自碱金属和铵,其可以被烷基化,R 2相同或不同,并且选自C 1 -C 20烷基和至少一种衍生自单羧酸,二元或多元羧酸或二胺的共配体, 至少一种过氧化物,每当量的CC双键使用多达4当量的过氧化物。
