A simple and mild Mn(OAc)3-promoted oxidative coupling of 1,4-dimethoxybenzenes with sodium and lithium sulfinates was developed. The reaction proceeded readily at room temperature in air, and various sulfones were synthesized in moderate to high yields. In addition, a straightforward approach for the conversion of organolithium reagents and sulfur dioxide into sulfonylated 1,4-dimethoxybenzenes was
开发了一种简单而温和的Mn(OAc)3促进1,4-二甲氧基苯与亚磺酸钠和亚磺酸锂的氧化偶联。该反应易于在室温下在空气中进行,并且以中等至高产率合成了各种砜。另外,探索了一种将有机锂试剂和二氧化硫转化为磺酰化的1,4-二甲氧基苯的简单方法。
