Abstract Formation of stable and small-sized palladium nanoparticles of diameter 9.4 nm was accomplished by a simple heating of Pd(OAc)2 in 1-octyl-1,2,4-triazolium trifluoroacetate ionic liquid under standard atmospheric hydrogen pressure. Palladium nanoparticles were characterized by XRD, SEM, TEM, and EDX analysis techniques. The application of an addition reaction of arylboronic acid to nitrostyrenes provided
摘要 通过在标准大气压氢压下,在 1-octyl-1,2,4-triazolium 三氟乙酸盐离子液体中简单加热 Pd(OAc)2,可形成直径为 9.4 nm 的稳定且小尺寸的钯纳米粒子。通过XRD、SEM、TEM和EDX分析技术表征钯纳米颗粒。芳基硼酸与硝基苯乙烯的加成反应以高产率提供了二芳基取代的产物。这种 Pd-NPs 能够通过简单的倾析程序回收,最多可重复使用四次,而不会对其催化活性产生任何影响。图形概要
