  摘要：

  铑（II）可以通过分子内的氮杂C–H插入反应有效地促进芳基氨基甲酸酯底物的活化和环化，从而生成苯并恶唑啉酮。对底物范围的研究表明，该反应在更不稳定的o -C（sp 3）-H键上进行了选择性芳族C（sp 2）-H胺化反应。反向二次KIE的观察结果（P H / P D = 0.42±0.03）表明，芳族亲电取代机理参与了芳基CH酰胺化反应。

  Superparamagnetic Fe3O4 nanoparticles were used to prepare primary carbamates as well as monosubstituted and N,N‐disubstituted ureas. This efficient phosgene‐free process used urea as an eco‐friendly carbonyl source in the presence of a biocompatible deep eutectic solvent (DES) to provide an inexpensive and attractive route that afforded the products in moderate to excellent yields.
