perfluoroalkylation of organic compounds is reported. This operationally simple approach occurs under mild conditions producing valuable new C-C bonds. The chemistry is driven by the ability of NCNDs to directly reach an electronically excited state upon light absorption, thereby successively triggering the formation of reactive radical species from simple perfluoroalkyliodides. Preliminary mechanistic
报道了使用富含胺的 N 掺杂碳纳米点 (NCND) 进行有机化合物的光化学自由基全氟烷基化。这种操作简单的方法发生在温和的条件下,产生有价值的新 CC 债券。这种化学反应是由 NCND 在吸收光后直接达到电子激发态的能力驱动的,从而连续触发从简单的全氟烷基碘化物形成反应性自由基物种。还报告了初步的机理研究。
Photo-Induced Atom-Transfer Radical Reactions Using Charge–Transfer Complex between Iodine and Tertiary Amine
In the presence of charge-transfer complexes between iodine and tertiary amines, the aqueous-medium atom-transfer radical reactions proceeded under visible light irradiation without the typical photocatalysts.
Aqueous-Medium Carbon–Carbon Bond-Forming Radical Reactions Catalyzed by Excited Rhodamine B as a Metal-Free Organic Dye under Visible Light Irradiation
radical addition–cyclization–trapping reactions under visible light irradiation. In the presence of (i-Pr)2NEt, the electron transfer from the excited rhodamine B to perfluoroalkyl iodides proceeded smoothly to promote the carbon–carbonbond-forming radical reactions in aqueous media. When i-C3F7I was employed as a radical precursor, the aqueous-medium radical reactions proceeded even in the absence of
