using water as the sole solvent in high yields. The efficient catalytic activity is mainly attributed to large specific surface area, increased number of active sites, solvent reorganization between the pores of mesoporous CuMnO nanoframework, and the various electronic states of the copper and manganese ions (Cu, Cu, Mn, Mn) due to the Jahn-Teller effect. This research provides new insights into improving
合成了具有介孔结构的混合金属氧化物(MMO)CuMnO 纳米框架。这种介孔MMO的优点是比表面积大、孔径均匀、金属价态多样。 MMO CuMnO 纳米框架在 2-氨基/羟基/巯基苯胺与各种醇的氧化偶联中表现出高效的催化活性,以水作为唯一溶剂高产率制备苯并咪唑、苯并恶唑和苯并噻唑。高效的催化活性主要归因于较大的比表面积、活性位点数量的增加、介孔 CuMnO 纳米框架孔隙之间的溶剂重组以及铜和锰离子 (Cu, Cu, Mn, Mn) 的各种电子态。达到扬-泰勒效应。该研究为提高催化剂合成含氮五元环化合物的催化性能提供了新的见解。
