  catalyst. The reaction proceeds readily in an open flask at room temperature without additional base, ligand, or additive. Rapid access to urea analogues via a two-step one-pot procedure is enabled by reacting N-arylcarbamates with aluminum–amine complexes. In addition, among several boronic acid derivatives prepared, dimethylphenyl boronate was found to react rapidly in its reaction with benzyl azidoformate

  N-芳基氨基甲酸酯的温和有效合成是通过在10 mol％氯化铜催化剂存在下使叠氮基甲酸酯与硼酸反应实现的。该反应在室温下在开放烧瓶中容易进行，无需额外的碱，配体或添加剂。通过使N-芳基氨基甲酸酯与铝-胺络合物反应，可以通过两步一锅法快速获得尿素类似物。另外，在制备的几种硼酸衍生物中，发现二甲基苯基硼酸酯在其与叠氮基甲酸苄酯的反应中快速反应，从而在催化循环中原位生成该物种。

  efficient “one-pot” approach to multiple substituted ureas from N-arylcyanamide and diaryliodonium salts has been presented. The two-step procedure involved the weak base-promoted chemoselective arylation of secondary amines with diaryliodonium and Cu-catalyzed nucleophilic addition of N-arylcyanamide with second diaryliodonium. The diverse unsymmetrical arylureas were obtained in up to 91% yield for 29 examples

  A two-coordinate Fe(II) m-terphenyl complex acts as a precatalyst for the hydroamination of isocyanates, affording urea and biuret derivatives, with product selectivity accomplished via modification of the reaction conditions. Using a more nucleophilic amine facilitates the insertion of up to four isocyanates into the N–H bond, affording triuret and tetrauret derivatives.
