Abstract
Palladium nanoparticles (PdNPs) with a size of 1.4 nm are stabilized by dendritic nanoreactors containing 1,2,3-triazole ligands with hydrophilic triethylene glycol (TEG) termini. These PdNPs are stable for months under air and are extremely active for the Suzuki-Miyaura reactions of aryl bromides down to sub-ppm levels.
摘要
钯纳米粒子（PdNPs）的尺寸为 1.4nm，由含有 1,2,3-三氮唑配体的树枝状纳米反应器稳定，其亲水端为三乙二醇（TEG）。这些 PdNPs 在空气中稳定数月，对芳基溴化物的 Suzuki-Miyaura 反应极为活泼，甚至可达到亚 ppm 级。
