摘要

作为有机合成和聚合物合成的新工具,光氧化催化在 21 世纪变得越来越普遍。此外,这一领域显然符合绿色化学十二项原则的期望。然而,获得含金属的光敏剂并不总是那么简单,可能需要较长的反应时间、使用有毒溶剂和多步合成。使用新技术可以克服这些缺点。在本报告中,我们利用球磨技术开发了一种一步法两步合成铁(II)光敏剂的方法。整个反应时间大大缩短,反应过程中不需要溶剂,而且可以高产率(73-99%)分离出十种配合物。利用透明的研磨罐,可以使用原位拉曼光谱跟踪复合物的形成过程。

Ball-milling for efficient synthesis of pyridine-containing iron(ii) photosensitizers†

Photoredox catalysis is becoming more and more prevalent in the 21st century as a new tool for organic and polymer synthesis. In addition, this domain clearly fits the expectations of the twelve principles of green chemistry. However, access to metal containing photosensitizers is not always straightforward and can require long reaction times, the use of toxic solvents and multi-step synthesis. These are definitely drawbacks that could be overcome with the use of novel technologies. In this report, we develop a one-pot two-step synthesis of iron(II) photosensitizers using ball-milling. Overall reaction times were drastically reduced, no solvent was needed during the reaction, and ten complexes could be isolated in high yields (73–99%). Using a transparent milling jar, the formation of the complexes could be followed using in situ Raman spectroscopy.
