This work describes a practical methodology for C-C bond formation reactions with the aid of biogenic palladium nanoparticles, which are synthesized by using phytochemicals extracted from two common plant species. Comparative studies have been done on the activity of two plant species ( and ) in generation of palladium nanoparticles via ex situ and in situ methods. The structural and morphological characteristics of the nanoparticles are examined by UV/visible spectroscopy, powder X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and transmission electron microscopy analyses. We have observed a significant influence of the substrates on the catalytic activity of the palladium nanoparticles in Sonogashira and Suzuki cross-coupling reactions.
这项工作描述了一种借助生物源钯纳米颗粒进行C-C键形成反应的实用方法，这些钯纳米颗粒是通过使用从两种常见植物物种中提取的植物化学物质合成的。已经通过异位和原位方法对两种植物物种（和）在生成钯纳米颗粒方面的活性进行了比较研究。通过紫外/可见光谱、粉末X射线衍射、X射线光电子能谱、傅里叶变换红外光谱和透射电子显微镜分析来检查纳米颗粒的结构和形态特征。我们观察到底物对钯纳米颗粒在Sonogashira和Suzuki交叉偶联反应中的催化活性有显著影响。
