树脂担载金催化剂可以高效、高选择性地催化氧化羰化胺制取对称二脲。例如，在使用苯胺作为反应物时，其转化频率达到了1475，选择性达到了99%。此反应中不需要加入其它溶剂，避免了溶剂引起的污染问题，同时催化剂与反应体系易分离，能够得到高纯度的产物。

Symmetric ureas were synthesized with high efficiency and selectivity by oxidative carbonylation of aromatic and aliphatic amines in the presence of resin immobilized gold, e.g. 1475 ofTOF and 99% of selectivity were achieved when using aniline as the substrate. No other organic solvent was used in the reactions and highly pure porducts could be obtained due to the high selectivity and the easy separation of the catalyst from the reaction system.
