So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Sun, Longjiang; Li, Qi; Zheng, Mang; Lin, Siying; Guo, Changliang; Luo, Laiyu; Guo, Shien; Li, Yuxin; Wang, Cheng; Jiang, Baojiang researched the compound: 1,10-Phenanthroline( cas:66-71-7 ).Product Details of 66-71-7.They published the article 《Efficient Suzuki-Miyaura cross-coupling reaction by loading trace Pd nanoparticles onto copper-complex-derived Cu/C-700 solid support》 about this compound( cas:66-71-7 ) in Journal of Colloid and Interface Science. Keywords: copper palladium nanocomposite catalyst preparation crystal structure; iodobenzene phenylboronic acid copper palladium catalyst Suzuki coupling; biphenyl preparation; Cu/C composite materials; Mononuclear copper complex; Suzuki-Miyaura cross-coupling (SMC) reaction; Synergistic effect; Trace Pd loading. We’ll tell you more about this compound (cas:66-71-7).
The development of efficient carbon-carbon cross-coupling catalysts with low noble metal amounts attracts much attention recently. Herein, a Cu/C-700/Pd nanocomposite is obtained by loading trace Pd2+ onto carbon support derived from a novel mononuclear copper complex, {[Cu(POP)2(Phen)2]BF4}. The as-prepared nanomaterial features the facial structure of highly dispersed copper phosphide nanoparticles as well as Pd nanoparticles via neighboring Cu-Pd sites. The Cu/C-700/Pd nanocomposite shows excellent catalytic activity (99.73%) and selectivity in Suzuki-Miyaura cross-coupling reaction, at trace Pd loading (0.43 mol%). Compared with the reported palladium nano catalysts, its advantages are proved. The appealing gateway to this stable, innovative and recyclability, Cu/C-700/Pd nanostructure recommends its beneficial utilization in carbon-carbon coupling and other environmentally friendly processes.
This literature about this compound(66-71-7)Product Details of 66-71-7has given us a lot of inspiration, and I hope that the research on this compound(1,10-Phenanthroline) can be further advanced. Maybe we can get more compounds in a similar way.
