A convenient photochemical flow protocol for the formation of aryl‐carbon bonds via photogenerated phenyl cations has been developed. A wide range of phenylated products, including biaryls, allylarenes, 2‐arylacetals and benzyl γ‐lactones, was smoothly synthesized in satisfactory yields under metal‐free conditions. The adoption of a flow reactor often allowed us to adopt higher concentrations of substrates
已经开发了通过光生苯基阳离子形成芳基碳键的便捷光化学流方案。在无金属条件下,可以令人满意的收率平稳地合成了多种苯基化产物,包括联芳基,烯丙基芳烃,2-芳基缩醛和苄基γ-内酯。与间歇式系统中通常使用的相比,采用流动反应器通常可以使我们采用更高浓度的底物和较短的辐照时间。
