Abstract

Herein, we report the radiosynthesis of F-difluoromethylarenes the assembly of three components, a boron reagent, ethyl bromofluoroacetate, and cyclotron-produced non-carrier added [F]fluoride. The two key steps are a copper-catalysed cross-coupling reaction, and a Mn-mediated F-fluorodecarboxylation.

摘要

在此,我们报告了F-二氟甲基芳烃的放射性合成,其由硼试剂、溴氟乙酸乙酯和回旋加速器产生的无载体添加的[F]氟化物三种组分组装而成。两个关键步骤是铜催化的交叉偶联反应和锰介导的F-氟脱羧反应。
