Herein, we report the radiosynthesis of 18F-difluoromethylarenes via the assembly of three components, a boron reagent, ethyl bromofluoroacetate, and cyclotron-produced non-carrier added [18F]fluoride. The two key steps are a copper-catalysed cross-coupling reaction, and a Mn-mediated 18F-fluorodecarboxylation.
在此,我们报告了通过三种组分(硼试剂、溴氟乙酸乙酯和回旋加速器产生的添加[ 18 F]氟化物的非载体)组装来放射合成18 F-二氟甲基芳烃。两个关键步骤是铜催化的交叉偶联反应和 Mn 介导的18 F-氟脱羧反应。
