First selenium ligand stabilized Pd(0) nanoparticles (∼3-5 nm) catalyze Suzuki-Miyaura C-C coupling in short time and are recyclable (up to 94% yield after 5 reuses). The air stable compound [PdCl(2)(L1)(2)] shows high catalytic efficiency for this coupling as its 3 × 10(-5) mol% is sufficient for activated ArBr.
首先,硒配体稳定的 Pd(0)纳米颗粒(∼3-5nm)可在短时间内催化 Suzuki-Miyaura C-C 偶联反应,且可回收利用(重复使用 5 次后产率高达 94%)。空气稳定的化合物 [PdCl2(L1)2] 对该偶联反应具有很高的催化效率,其 3×10-5mol%就足以激活 ArBr。
