Radical conjugate addition onto vinyl sulfones was achieved by means of a convenient, tin-free procedure. This was based on the photocatalyzed CH bond activation in aldehydes, amides, ethers and even cycloalkanes by using tetrabutylammonium decatungstate (TBADT). The reaction was likewise effective for the functionalization of β-substituted vinyl sulfones. The products are useful building blocks and
通过方便的无锡方法将自由基共轭物加成到乙烯基砜上。这是基于使用四丁基癸酸铵(TBADT)在醛,酰胺,醚甚至环烷烃中的光催化CH键活化。该反应对于β-取代的乙烯基砜的官能化同样有效。该产品是有用的结构单元,在人造紫外线和日光下均能以令人满意的收率获得,因此证明了该工艺的“绿色”潜力。
