受阻路易斯酸碱对的构建及其在小分子活化中的应用是一个十分重要的研究课题.论文探讨高活性锗基受阻路易斯酸碱对的合成及反应活性研究,为小分子活化体系的构建提供理论和实验依据.利用具有强路易斯酸性的有机锗化合物与二叔丁基甲基膦反应合成分子内受阻路易斯酸碱对,发现该锗基受阻路易斯酸碱对具有较高的反应活性,与全氟苯基上的C-F键进行插入反应生成离子型化合物8.

The construction of frustrated Lewis pairs(FLP)and their application in small molecule activation is a very important topic.In this paper,the synthesis and reactivity of a germanium frustrated Lewis pair with high activity are investigated,which provide the theoretical and experimental basis for the construction of small molecular activation system.By using organic germanium compound as strong Lewis acid to react with di-tert-butyl methylphosphine to synthesize intramolecular frustrated Lewis pairs,it is found that the germanium frustrated Lewis pairs has high reactivity,and the C-F bonds on perfluorinated phenyl groups are inserted in the reaction to form ionic compound 8.
