摘要：

Novel combined PdCl 2(RuCl 3) with ZrO 2 SO 3 catalysts were developed for the synthesis of carbamates by oxidative carbonylation of aliphatic and aromatic amines. At 170 ℃ and 4.0 MPa, oxidative carbonylation of aromatic amines to the corresponding carbamates over this catalyst system could be proceeded with a high conversion and selectivity. Especially when β naphthylamine was used as the substrate, 100% conversion and 95% selectivity were obtained in only 15 min. The catalytic performance of PdCl 2/ZrO 2 SO 3 was better than that of RuCl 3/ZrO 2 SO 3 for such oxidative carbonylation reaction. Possible role of ZrO 2 SO 3 as co catalyst was also conjectured.
