We report the development of a silicon nanowire array‐stabilized palladium nanoparticle catalyst, SiNA‐Pd. Its use in the palladium‐catalyzed Mizoroki‐Heck reaction, the hydrogenation of an alkene, the hydrogenolysis of nitrobenzene, the hydrosilylation of an α,β‐unsaturated ketone, and the C‐H bond functionalization reactions of thiophenes and indoles achieved a quantitative production with high reusability
我们报告了硅纳米线阵列稳定的钯纳米粒子催化剂SiNA-Pd的开发。它在钯催化的Mizoroki-Heck反应,烯烃的氢化,硝基苯的氢解,α,β-不饱和酮的氢化硅烷化以及噻吩和吲哚的C-H键官能化反应中的应用实现了定量生产具有很高的可重用性。钯的催化活性达到数百mol ppb,TON达到2000000。
