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
报道了一种新的无过渡金属路线,用于在 TMSOTf 存在下用芳基亚磺酸钠直接亚磺酰化富电子芳烃。各种富电子芳烃,包括吡咯、噻吩、吲哚和富电子芳烃,与芳基亚磺酸钠一起以中等至极好的收率转化为相应的亚砜。该协议具有许多优点,例如易于获得且稳定的起始材料、广泛的底物范围和无过渡金属的反应条件。
