The use of readily available hydroxamic acids as reagents for the chemoselective (ortho‐amino)arylation of amides is described. This reaction proceeds under metal‐free, mild conditions, displays a very broad scope, and constitutes a direct approach for the metal‐free attachment of aniline residues to carbonyl derivatives.
描述了使用现成的异羟肟酸作为酰胺化学选择性(邻氨基)芳基化反应的试剂。该反应在无金属,温和的条件下进行,显示范围很广,是苯胺残基与羰基衍生物无金属连接的直接方法。
