By employing a silica-coated magnetite as a catalyst, a silica-catalyzed carboxylative cyclization of propargylic amines with carbon dioxide (CO2) proceeded to afford the corresponding 2-oxazolidinones. Moreover, after the reaction, the silica-coated magnetic catalyst was readily recovered by use of an external magnet and could be reused up to six times without deactivation.

二氧化硅包覆磁铁矿催化 CO2 羧化炔丙胺

通过使用二氧化硅包覆的磁铁矿作为催化剂,进行二氧化硅催化的炔丙胺与二氧化碳 (CO 2 ) 的羧化环化反应,得到相应的 2-恶唑烷酮。此外,反应后,二氧化硅包覆的磁性催化剂通过使用外部磁铁很容易回收,并且可以重复使用多达六次而不会失活。
