报道了以二芳基硫鎓盐、芳基丙酸盐和二氧化硫为原料合成磺化香豆素的新方法。反应在温和的室温条件下进行，没有任何催化剂。这种转变完全由可见光驱动，并通过直接掺入二氧化硫为砜的可持续合成开辟了新的机会。
A novel 3-component synthesis of sulfonylated coumarins from diaryliodonium salts, arylpropynoates and sulfur dioxide is reported. The reaction proceeds under mild conditions at room temperature in the absence of any catalysts. This transformation is solely driven by visible light and opens a new opportunity for the sustainable synthesis of sulfones via the direct incorporation of sulfur dioxide.
