Abstract
1,4-Bis[trimethylsilyl(ethynyl)]naphthalene () and 1,4-bis[trimethylsilyl(ethynyl)]anthracene () undergo diastereoselective coupling with Cp2Zr(py)(Me3SiC[triple bond, length as m-dash]CSiMe3) to give trimeric macrocycles in good yield.
摘要
1,4-双[三甲基硅基（乙炔基）]萘（）和1,4-双[三甲基硅基（乙炔基）]蒽（）与Cp2Zr(py)(Me3SiC≡CSiMe3)发生非对映选择性偶联反应，以良好的产率生成三聚大环化合物。
