Dimethyl 2-vinylcyclopropane-1,1-dicarboxylate underwent a hydrophosphination reaction with either a primary or secondary phosphine under photolytic conditions. Notably, a free radical initiator was not required. The resulting tertiary phosphines were derivatized using S8 to afford moisture and air stable yellow or colorless oils in a 27%–73% isolated yield. A series of control reactions were performed
2-乙烯基环丙烷-1,1-二羧酸二甲酯在光解条件下与伯膦或仲膦发生氢膦化反应。值得注意的是,不需要自由基引发剂。使用 S 8对生成的叔膦进行衍生化,以 27%–73% 的分离收率提供对水分和空气稳定的黄色或无色油状物。进行了一系列控制反应,我们提出这种 UV 诱导的磷酸氢化反应通过自由基机制进行。
