We present a photo- and Cu-mediated 11C cyanation of bench-stable (hetero)aryl thianthrenium salts via an aryl radical addition pathway. The thianthrenium substrates can be readily accessed via C–H functionalization, and the radiocyanation protocol proceeds under mild conditions (<50 °C, 5 min) and can be automated using open-source, readily accessible augmentations to existing radiochemistry equipment
我们提出了通过芳基自由基加成途径对实验室稳定的(杂)芳基噻烯盐进行光和铜介导的11 C 氰化。铊底物可以通过 C-H 官能化轻松获得,放射氰化方案在温和条件下(<50°C,5 分钟)进行,并且可以使用开源、易于访问的现有放射化学设备增强功能实现自动化。
