Photoinduced radical perfluoroalkylation of various simple electron-deficient olefins was achieved in the presence of an aqueous Na2S2O3 solution. The reactions proceeded smoothly to give addition or addition–elimination products. The ability of the products to be used as radical precursors or Michael acceptors was also demonstrated.
在Na 2 S 2 O 3水溶液的存在下,实现了各种简单的缺电子烯烃的光诱导自由基全氟烷基化。反应进行顺利,得到加成或加成消除产物。还证明了该产品用作自由基前体或迈克尔受体的能力。
