synthesis of functionalized biaryls through nucleophilic aromatic substitution (SNAr) of arylhydroxylamines to arylsulfonium salts. With this protocol, structurally diverse functionalized biaryls were obtained smoothly in moderate to good yields. Merits of this transformation include mild reaction conditions, broad substrate scope, great functional group tolerance, feasibility of a one-pot procedure, and
我们报告了一种无过渡金属方案,用于通过芳基羟胺到芳基锍盐的亲核芳族取代 (S N Ar) 合成功能化联芳基化合物。使用该协议,结构多样的功能化联芳基以中等至良好的产量顺利获得。这种转化的优点包括反应条件温和、底物范围广、官能团耐受性好、一锅法的可行性以及易于处理和放大。
