摘要
这项工作的重点是开发和表征高效的 CuI/MnO2 纳米催化剂,并使用 XPS、XRD、EDAX、傅立叶变换红外光谱、FESEM、BET(表面积:8 01 m2/g,孔径:17 052 Å,孔体积:0 011 cm3/g)和 TEM 技术对其进行表征:8.01 m2/g,孔半径:17.052 Å,孔体积:0.011 cm3/g)和 TEM 技术进行表征。在通过邻苯二胺与苯甲醛缩合合成具有生物活性的 2-取代苯并咪唑时,对该催化剂的反应活性进行了评估。该工艺具有反应时间短、吨重高(997.35)、绿色条件、产率高、易于操作、绿色指标值好等特点,如低 E 系数(0.17)和过程质量效率(PMI)(1.16)、高反应质量效率(RME)值(91.2 %)和碳效率(CE)(94 %),这些都是合成催化剂的良好特性。
CuI/MnO2 nanocatalysed synthesis of bioactive 2-substituted benzimidazoles
This work focusses on the development and characterization of efficient CuI/MnO2 nano catalyst, characterized using XPS, XRD, EDAX, FTIR, FESEM, BET (surface area: 8.01 m2/g, a pore radius: 17.052 Å and a pore volume: 0.011 cm3/g) and TEM techniques. The reactivity of this catalyst was evaluated for the synthesis of biologically active 2-substituted benzimidazoles through condensation of o-phenylenediamine with benzaldehydes. The process features short reaction time, high TON (997.35), green conditions, high yield, easy work-up, good green metrices values such as low E-factor (0.17) and Process mass efficiency (PMI) (1.16) high Reaction mass efficiency (RME) value (91.2 %) and carbon efficiency (CE) (94 %) are good characteristics of the synthesized catalyst.
期刊介绍:
Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
