锆杂环化合物因其多种反应活性而备受关注.2分子1,1-二取代联烯在低价锆物种“Cp2Zr(II)”作用下可发生分子间还原偶联形成α,α’-双亚甲基锆杂环戊烷,反应的区域及立体化学受到取代基空间效应影响显著.α,α’-双亚甲基锆杂环戊烷中含有两个sp2碳-金属键,与多种亲电试剂体系反应分别生成多种类型有机分子,可为2,5-二卤代-1,5-己二烯、具有1,5-二烯骨架的1,6-二羰基化合物等多功能有机分子提供新合成方法学.
Zirconium heterocyclic compounds have drawn much attention due to their various reactivity.2 molecular 1,1 -disubstituted alkenes can undergo reductive coupling between molecules under the action of the low-valent zirconium species “Cp2Zr (II)” to form α, α’-bis (methylene) zirconium heterocyclopentane, the reaction region and stereochemistry are greatly affected by the steric effect of the substituents.α, α’-bis (methylene) zirconium heterocyclopentane contains two sp2 carbon-metal bonds , React with a variety of electrophile systems to generate various types of organic molecules, which may be 2,5-dihalo-1,5-hexadiene, 1,6-dicarbonyl having a 1,5-diene skeleton Compounds and other multi-functional organic molecules provide a new synthesis methodology.
