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
