摘要

合成了一种由对甲苯磺酸（PTSA）和聚乙二醇 200（PEG200）组成的深共晶溶剂（DES），并将其应用于 2-金刚烷酮的拜尔-维里格（B-V）氧化反应，在相对温和的条件下表现出良好的催化效果和循环稳定性。研究发现，DES 的氢键不仅决定其物理性质，如粘度和导电性，还影响其化学行为，包括在 B-V 氧化反应中的催化作用。通过调整成分，可以优化氢键特性。本研究旨在阐明 DESs 的组成、氢键强度和理化性质之间错综复杂的关系，从而为全面了解和构建 DESs 系统奠定初步的理论基础。这为 B-V 氧化反应提供了一种新颖且有前景的环境友好型方法。

Efficient catalysis for the Baeyer-Villiger oxidation reaction of 2-adamantone in acidic deep eutectic solvents

A deep eutectic solvent (DES) comprising p-toluenesulfonic acid (PTSA) and polyethylene glycol 200 (PEG200) was synthesized and applied to the Baeyer-Villiger (B-V) oxidation reaction of 2-adamantanone, which exhibited good catalytic effect and cyclic stability under relatively mild conditions. It was found that the hydrogen bond of DESs not only governed their physical properties, such as viscosity and electrical conductivity, but also influenced their chemical behavior, including the catalytic effect in B-V oxidation reaction. By adjusting the composition, the hydrogen bond properties can be optimized. This study aims to elucidate the intricate relationship between composition, hydrogen bond strength, and physicochemical properties of DESs, thereby establishing a preliminary theoretical foundation for a comprehensive understanding and construction of DESs systems. This provides a novel and promising environmentally friendly approach for the B-V oxidation reaction.
