| 摘要: 1,5-环辛二烯(简称COD)是丁二烯环化二聚产物。1,3-环辛二烯是新型的有机合成中间体和高分子单体。近年来,陆续出现了一些报道用过渡金属配合物作为均相催化剂,使非共轭的1,5-COD异构化为共轭的1,3-COD,并先后提出了几种不同的反应机理。 |

| Abstract: The isomerization of 1,5-COD can be catalyzed by Cp2Ni/i-C3H7MgBr into 1,4-COD and 1,3-COD. The mechanism of isomerization is proposed as scheme 1. The compounds CpNi(η3-c-C8H13),Ni(COD)2 and Mg4Br6O·4Et2O were isolated and characterized from reaction mixture, and therefore the reactions between Cp2Ni/i-C3H7MgBr and COD can be represented as shown in scheme 2. |
