A novel diethylzinc-mediated radical 1,2-addition of perfluoroalkyl iodides to unactivated alkenes and alkynes is presented, which demonstrates a novel way to generate an ethyl difluoroacetate radical. This method is highly efficient and gives full conversions of the substrates, high yields of the products, and negligible byproducts and requires no column chromatography purifications. The mild conditions
提出了一种新颖的由二乙基锌介导的全氟烷基碘与非活化烯烃和炔烃进行的1,2-基自由基加成反应,这表明了一种生成二氟乙酸乙酯基团的新方法。该方法非常高效,可实现底物的完全转化,产物的高收率和可忽略的副产物,并且不需要柱色谱法纯化。温和的条件使该协议能够表现出出色的官能团兼容性。
