nanoparticles. SARu is an ideal ruthenium catalyst for liquid-phase combinatorial synthesis because it repeatedly catalyzes ligand-free Suzuki–Miyaura coupling of aryl halides, including aryl chlorides, with arylboronic acids with low Ru leaching. Physical analysis of SARu showed that the active species in these reactions were ruthenium (0) nanoparticles with a size of 1–3 nm. Also, we developed a continuously
我们开发了一种概念上和方法上新颖的钌(0)纳米颗粒催化剂,硫改性的金负载钌纳米颗粒(SARu)。SARu可以很容易地通过包括原位同时进行的三步过程来制备金属纳米粒子和纳米空间组织。这种独特的方法不需要任何常规的预制模板即可固定和稳定金属纳米颗粒。SARu是液相组合合成的理想钌催化剂,因为它反复催化无配体的无配体的Suzuki-Miyaura偶联,使芳基卤化物(包括芳基氯化物)与低Ru浸出的芳基硼酸发生反应。SARu的物理分析表明,这些反应中的活性物质为钌(0)纳米粒子,大小为1-3 nm。此外,我们开发了一种连续辐射微波方法,该方法可以首次区分微波实验中的加热效果和微波效果。
