Abstract

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.

CuI/MnO2 纳米催化合成具有生物活性的 2-取代苯并咪唑

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。
