a member of 14th group that falls between Si and Sn, has remained considerably ignored as a nucleophile for a long time. Compared with other forms of Ge-containing nucleophiles, germatranes are structure-defined, easily accessible, and stabilized nucleophilic fragments, but they fail to meet the need of high reactivity and facile introducing to organics. Herein, we report a modified structure of germatranes
属于Si和Sn之间的第14族成员中的锗,作为亲核试剂长期以来一直被忽略。与其他形式的含Ge亲核试剂相比,胚芽烷具有结构定义,易于获取和稳定的亲核片段,但不能满足高反应活性和易于引入有机物的需求。在本文中,我们报告了一种修饰的金刚烷的结构,其交叉偶联反应性得到了极大的改善。该结构可以容易地由廉价的工业GeO 2构造,并且在容易的转变后也可以获得相应的Ge -Cl和Ge -H。此外,AR-戈 可以从格氏试剂或钯催化的芳基卤化物的杀菌反应中有效合成。
