efficiency as a tool for high-throughput screening (HTS) of transition-metal-catalyzed coupling reactions was investigated. It showed a high selectivity for halide ions. When the PAR–2Hg2+ complex was used in the Suzuki coupling reaction and C–H activated coupling reaction with aryl bromides, the quantitative and qualitative conversions of aryl halides were obtained from the reaction mixture color change
制备了4-(2-吡啶基偶氮)间苯二酚(PAR-2Hg 2+)的汞络合物,卤离子化学传感器,其作为过渡金属催化的偶联反应高通量筛选(HTS)的工具的效率为调查。它显示出对卤离子的高选择性。当将PAR-2Hg 2+络合物用于Suzuki偶联反应和CH-H与芳基溴的活化偶联反应时,从反应混合物的颜色变化获得了芳基卤化物的定量和定性转化。
