摘要 //

A new transition-metal-free route for the direct sulfinylation of electron-rich aromatics with sodium arylsulfinates in the presence of TMSOTf is reported. Various electron-rich aromatics, including pyrroles, thiophenes, indoles, and electron-rich arenes, with sodium arylsulfinates are converted into the corresponding sulfoxides in moderate to excellent yields. This protocol possesses many advantages such as readily available and stable starting materials, broad substrate scopes, and transition-metal-free reaction conditions. 

报告了在一种在 TMSOTf 存在下，用芳基亚磺酸钠直接亚磺酰化富电子芳烃的无过渡金属新途径。各种带有芳基亚磺酸钠的富电子芳族化合物，包括吡咯、噻吩、吲哚和富电子芳烃，均以中等至优异的收率转化为相应的亚砜。该方案具有原料易得、稳定，底物范围广，反应条件中无过渡金属等优点。
