The metal- and photocatalyst-free synthesis of substituted allylarenes has been carried out under visible light driven conditions. The process was based on the photogeneration of aryl radicals from arylazo sulfones and their ensuing reaction with allyl sulfones. The developed procedure was very efficient when using substrates bearing electron-withdrawing groups, and allowed for the preparation of α-benzyl styrenes and 2-benzyl acrylates in good yields.
在可见光驱动条件下，实现了无金属和光催化剂条件下取代的烯丙基芳烃的合成。该过程基于芳基偶氮砜在光照下生成芳基自由基，然后与烯丙基砜反应。当使用带有吸电子基团的底物时，该方法非常有效，可得到高产率的α-苄基苯乙烯和 2-苄基丙烯酸酯。
