过渡金属杂环化合物特别是过渡金属杂小环化合物(成环原子数小于6)在金属有机化学和配位化学领域中具有重要的地位,它们是许多过渡金属催化反应包括烯烃复分解反应、炔烃聚合反应的中间体.通常过渡金属杂小环化合物具有较大的环张力,因此极易与不饱和化合物反应生成环张力较小的扩环产物.针对过渡金属杂小环化学研究现状,综述了几类典型的过渡金属杂三、四、五元环的扩环反应.
Transition metal heterocyclic compounds, especially transition metal heterocyclic compounds (number of ring-forming atoms less than 6), play an important role in the fields of metal organic chemistry and coordination chemistry. They are many transition metal-catalyzed reactions including olefin metathesis reactions, Polymerization intermediates usually transition metal heterocyclic compounds have a larger ring tension, and therefore easily react with unsaturated compounds to produce ring tension smaller expansion products.For the current status of transition metal heterocycles, we reviewed Several typical transition metal heterotrimes, four, five ring expansion reaction.
