An efficient three-step synthesis of germyl linker precursor 4 is described which enables a simple two step immobilisation of lithiated aromatics to Argogel™ polymer; cleavage from the polymer support via ipso-degermylation with TFA, ICl, Br2 and NCS provides protio-, iodo-, bromo- and chloro- aryls, respectively.
描述了一种高效的三步合成方法,制备了锗基链接前体4,这使得锂化芳烃的简单两步固定化成为可能;通过与TFA、ICl、Br2和NCS的ipso去锗化反应,从聚合物支持物中断裂,分别得到质子芳烃、碘芳烃、溴芳烃和氯芳烃。
