A transition-metal-free approach for the arylation of hydroxylamines and oximes with diaryliodonium salts was developed. The reaction proceeded smoothly at room temperature in the presence of cesium carbonate. As a result, a wide range of N- and O-arylated hydroxylamines were synthesized in good to excellent yields (45-98%).
开发了一种不含过渡金属的方法,用于羟胺和肟与二芳基碘盐的芳基化。在碳酸铯存在下,反应在室温下顺利进行。结果,合成了多种 N- 和 O- 芳基化羟胺,产率良好至极好 (45-98%)。
