A crowned manganese-based Schiff complex supported on nanocellulose as an efficient and sustainable heterogeneous catalyst for the oxidation of benzyl alcohols

In this study, a Schiff- base- manganese complexes containing crown ether ring synthesized, immobilized on nanocellulose (MnL2@nanocellulose) and characterized by FT-IR, H -NMR, EDX, UV-Vis, microanalysis (CHN and ICP) and SEM. This catalyst was used for the oxidation of benzyl alcohols and its performance was compared with the analogue without crown ether (MnL 1 @nanocellulose). The results showed that MnL 2 @nanocellulose had much better catalytic activity despite the lower Mn content. (c) 2023 Elsevier B.V. All rights reserved.

Automated summary

In this study, a Schiff-base-manganese complex containing a crown ether was synthesized and immobilized on nanocellulose (MnL2@nanocellulose) for catalytic oxidation of benzyl alcohols. Characterization techniques including FT-IR, H-NMR, EDX, UV-Vis, microanalysis (CHN and ICP) and SEM were used. Compared to the analogue without crown ether (MnL1@nanocellulose), MnL2@nanocellulose exhibited better catalytic activity despite having a lower Mn content. (c) 2023 Elsevier B.V. All rights reserved.
