visible light mediated addition of sulfenyl radicals to trialkyl phosphites to access functionalized phosphorothioates. The use of cheap and readily available Eosin Y as a photocatalyst under mild energy efficient conditions bypassing the use of external oxidants forms the chief highlight of the work. The protocol is scalable and mechanistic studies indicate that the reaction proceeds through an ionic-Arbuzov
我们在此公开了一种可见光介导的亚磷酸三烷基酯加成亚硫基自由基来获得功能化的硫代磷酸酯。在温和的节能条件下,绕过使用外部氧化剂,使用廉价且容易获得的曙红 Y 作为光催化剂,这是这项工作的主要亮点。该协议是可扩展的,机械研究表明,该反应通过磷酰基自由基的离子-Arbuzov 样途径进行。
Copper(I) Iodide Catalyzed Synthesis of Thiophosphates by Coupling of H-Phosphonates with Benzenethiols
benzenethiols. The method involves copper(I) iodidecatalyzed coupling of thiols with H-phosphonates in the presence of triethylamine. The reaction proceeds effectively to afford the corresponding thiophosphates in moderate to good yields via an aerobic dehydrogenative coupling of H-phosphonates with benzenethiols. This method is easy, rapid, and good-yielding for the synthesis of thiophosphates from benzenethiols
