Herein, we demonstrate for the first time that coumarins derived from [2.2]paracyclophane (pCp) can act as effective organo-photocatalysts and promote the reductive cleavage of sulfonamides under light-irradiation. In the presence of these original compounds, photodesulfonylation reactions occur under mild conditions at low catalyst loadings in the presence of Hantzsch ester. Theoretical and experimental
在此,我们首次证明源自[2.2]对环芳烷(pCp)的香豆素可以作为有效的有机光催化剂并促进磺酰胺在光照射下的还原裂解。在这些原始化合物存在下,光脱磺酰化反应在 Hantzsch 酯存在下、在低催化剂负载量的温和条件下发生。描述了理论和实验研究,阐明了光催化过程中涉及的反应机理和活性物质的性质。这项概念验证研究为 pCps 在光催化领域的进一步应用铺平了道路。
