Disilacycloalkadienes with bridged halophenylene rings have been successfully synthesized via ring-closing metathesis reactions. Molecular structures of these macrocycles were fully characterized by NMR spectroscopies and X-ray crystallography. The Sonogashira coupling reactions of the macrocycles with phenylacetylene did not proceed probably owing to severe steric hindrance during the reactions.
通过闭环复分解反应成功合成了具有桥联卤代亚苯基环的二硅杂环二烯。这些大环化合物的分子结构通过核磁共振波谱和 X 射线晶体学得到了充分表征。大环化合物与苯乙炔的Sonogashira偶联反应没有进行可能是由于反应过程中严重的空间位阻。
