中文摘要: 以一些活性分子特别是目前在可见光催化条件下可以产生各种转化的化合物为起始原料,利用它们在体系中产生的中间体,研究与各种类型的氟化试剂的反应情况。本项目研究内容主要分为三个部分:1.考察含氮(三级胺,二级胺)化合物在可见光以及光氧化还原催化剂促进下与氟化试剂的氟化反应,并总结其规律; 2.对不饱和羰基类化合物在光催化条件下进行氟化反应研究; 3. 对含卤素的不饱和烃进行光催化的氟化反应研究。

英文摘要: The photoredox catalysis is attributed to the excited state of photoredox catalysts generated by irradiation of visible light, which is able to serve not only as a 1e-oxidant but also as a 1e-reductant. Their redox potentials are dependent on the structure and a key factor of efficient production of organic radicals. This project comprises three parts: 1) to investigate the fluorination of amines under visible-light-driven photoredox catalysis and summarize the regularity; 2) to research the fluorination of unsaturated carbonyl compounds and realize the cyclization/fluorination of the special substrates; 3) to further achieve the fluorination of unsaturated alkanes including halogen in the presence of photoredox catalyst.
