Abstract

The Front Cover features an abstract representation of two novel, highly reducing organophotocatalysts derived from N-arylphenothiazines and N,N-diarylphenazines, compounds widely recognized as versatile and effective photoredox catalysts. The catalysts shown are the most efficient from a library of 17 catalysts synthesized. They show remarkable performance in the addition of methanol to α-methylstyrene, which was used as a model reaction, significantly reducing the reaction time and the catalyst loading by more than 20 times. Alongside the featured catalysts, the cover shows abstract representations of photophysical and photocatalytic concepts. The authors used spectroelectrochemistry and DFT calculations to further elucidate their findings and derive structure–activity relationships that might help to further improve organophotocatalysts. More information can be found in the Research Article by H.-A. Wagenknecht and co-workers (DOI: 10.1002/ejoc.202400847).

封面:N-Arylphenothiazines and N,N-Diarylphenazines as Tailored Organophotoredox Catalysts for the Reductive Activation of Alkenes (Eur. J. Org. Chem. 40/2024)
封面摘要介绍了两种新型高还原性有机光催化剂,它们分别来自 N-芳基吩噻嗪和 N,N-二芳基吩嗪,这两种化合物被广泛认为是多功能、高效的光氧化催化剂。图中展示的催化剂是从合成的 17 种催化剂库中最有效的催化剂。它们在甲醇与 α-甲基苯乙烯的加成反应中(该反应被用作模型反应)表现出卓越的性能,大大缩短了反应时间,催化剂负载量减少了 20 多倍。在介绍特色催化剂的同时,封面还抽象地展示了光物理和光催化概念。作者利用光谱电化学和 DFT 计算进一步阐明了他们的发现,并推导出结构-活性关系,这可能有助于进一步改进有机光催化剂。更多信息请参阅 H.-A. Wagenknecht 及其合作者的研究文章。Wagenknecht 及其合作者的研究文章中(DOI: 10.1002/ejoc.202400847)。
