Synthesis of Ni@Au Core-shell Nanoparticles and Its Applications in ullmann reaction as a Synergistic Catalyst

Chinese Journal of Structural Chemistry 2011年第8期30卷 1122-1126页

作者：祁刚张银华 Department of Chemistry and Biology Yancheng Institute of Technology Yancheng Huaye Pharmaceutical and Chemical Company

The Ni@Au core-shell nanoparticles had been successfully synthesized from aqueous solution by one-step route at room temperature. The Ni@Au nanoparticles can be an excellent catalyst for ullmann reaction. The advantage of Ni@Au is that the catalyst does not need additional reducing agents. The Au shell can effectively protect the Ni core from oxidation. The Ni core and Au shell have both composited in structure and cooperated in function.

CuCl2/8-Hydroxyquinoline-catalyzed α-Arylation of Diethyl Malonate with Aryl Bromides

引用

Chemical Research in Chinese Universities 2018年第5期34卷 727-731页

A general and efficient coupling of aryl bromides with diethyl malonate is presented. The reaction provided the α-arylated diethyl malonates in moderate to good yields with a low loading of CUC12（5%, molar fraction） and 8-hydroxyquinoline（5% , molar fraction）. This method has good compatibility for a wide range of aryl bromides.

Cul/8-Hydroxyquinalidine Promoted N-Arylation of Indole and Azoles

引用

Chinese Journal of Chemistry 2012年第4期30卷 875-880页

作者：杨新业邢辉张烨赖宜生张奕华蒋咏文马大为 Center of Drug Discovery China Pharmaceutical UniversityNanjing 210009China State Key Laboratory of Bioorganic and Natural Products Chemistry Shanghai Institute of Organic ChemistryChinese Academy of SciencesShanghai 200032China

An efficient catalytic system of CuI/8-hydroxyquinalidine was developed for the coupling of aryl iodides and indole as well as some azoles. The reaction could be carried out at 90 ~C under the condition of relatively low cata- lyst loading, affording various N-arylindoles and N-aryl azoles in good yields. The functionalized and hindered aryl iodides were suitable substrates for this transformation.
