摘要
A cost-effective and step-economic synthesis of pharmaceutically important 1,2-disubstituted benzimidazoles and 2,3-dihydro-1H-perimidine derivatives is accomplished without the assistance of external ligands. An environmentally friendly biogenic strategy for the synthesis of single phase δ-MnO2 NPs using the Pongamia pinnata leaf extract was adopted. The phytochemicals detected in the extract of Pongamia pinnata leaves might be responsible for the reduction of Mn(VII) to Mn(IV), which provides stability to the metal centre. The synthesized catalyst was tested for the synthesis of pharmaceutically important benzimidazole and perimidine analogues. In addition, mechanistic experiments and the plausible mechanism were discussed. The δ-MnO2 NP catalyst exhibited superior catalytic activity and high durability in the dye removal study.

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
