仿生四齿胺基吡啶锰配合物(Mn-N4)已在各种选择性氧化反应中展示出优异的催化活性。本文我们报道了一系列 Mn-N4 的合成及其在催化仲醇氧化中的应用。该方法利用过氧化氢(H2O2)作为环境友好的氧化剂,并加入少量乙酸作为添加剂。值得注意的是,该催化剂体系的连续流工艺实现了快速转化,将反应时间从传统间歇体系的90分钟缩短到连续流工艺中的停留时间1.6分钟。这种方法为仲醇的工业氧化提供了一种有前途且实用的策略,显示出更广泛的应用潜力。

Bioinspired manganese complexes with tetradentate aminopyridine ligands (N4) have shown excellent promise as effective catalysts for various selective oxidation reactions. In this study, we report the synthesis of a series of Mn-N4 and their application in the catalytic oxidation of secondary alcohols. This method utilizes hydrogen peroxide as an environmentally benign oxidant, with a small amount of acetic acid as an additive. Notably, the continuous-flow process using this catalyst system achieves rapid conversion, reducing the reaction time from 90 min in a traditional batch system to 1.6 min residence time in the continuous-flow process. This approach offers a promising and practical strategy for the industrial oxidation of secondary alcohols, demonstrating significant potential for broader applications.
