The present invention relates to a process for the preparation of compounds or a mixture of compounds of the general formulae I.a or I.b wherein R1 is selected from C1-C12-alkyl, C3-C6-cycloalkyl, -C(=O)OR2, -PO(OR2a)2, aryl and hetaryl, R2, R2a are independently of each other selected from the group consisting of hydrogen,C1-C12-alkyl, C1-C12-alkenyl, where the last two radicals mentioned are unsubstituted, partly or completely halogenated or substituted by 1, 2, 3 or 4 radicals selected from the group consisting of C1-C6-alkoxy and CN, C3-C6-cycloalkyl, C3-C6-cycloalkyl-C1-C4-alkyl, aryl and aryl-C1-C4 -alkyl, where the last four radicals mentioned are unsubstituted or substituted by 1, 2, 3 or 4 radicals selected from the group consisting of C1-C6-alkyl, C1-C6-haloalkyl, C1-C6-alkoxy, C1-C6-haloalkoxy, -CN, and halogen, which comprises dimerizing olefin compound of the general formula II, in the presence of at least one N-heterocyclic carbene catalyst.
本发明涉及一种制备化合物或通式I.a或I.b混合物的方法,其中R1选自C1-C12烷基,C3-C6环烷基,-C(=O)OR2,-PO(OR2a)2,芳基和杂芳基,R2,R2a分别选自氢,C1-C12烷基,C1-C12烯基,其中上述最后两个基团未取代,部分或完全卤代或由选自C1-C6烷氧基和CN,C3-C6环烷基,C3-C6环烷基-C1-C4烷基,芳基和芳基-C1-C4-烷基的1,2,3或4个基团取代,其中上述最后四个基团未取代或由选自C1-C6烷基,C1-C6卤代烷基,C1-C6烷氧基,C1-C6卤代烷氧基,-CN和卤素的1,2,3或4个基团取代,包括在至少一种N-杂环卡宾催化剂的存在下,使通式II的烯烃化合物发生二聚化反应的方法。
