A novel visible-light-catalyzed sulfonylation/arylation of carbon–carbon σ-bond with sulfonyl chlorides for the synthesis of 3-sulfonylated 1,2-dihydronaphthalenes is developed. This difunctionalization proceeds via a sequence of C═C bond sulfonylation, C–C σ-bond cleavage, and intramolecular cyclization, and the experiment result shows that the C–C σ-bond difunctionalization reaction includes a radical
开发了一种新型的可见光催化的碳-碳σ键与磺酰氯的磺酰化/芳基化反应,用于合成3-磺酰化的1,2-二氢萘。这种双官能化通过一系列C═C磺酰基化,CCσ键裂解和分子内环化过程进行,实验结果表明,CCσ键双官能化反应包括一个自由基过程。该策略为一键式C–S键和一个新的C–C键的构建提供了一条简单且方便的途径,用于将C–C键与芳族碳和磺酰基进行双官能化。
