Copper( i ) anchored on a covalent triazine framework/ionic liquid as a recyclable catalytic system for cyclization of propargylic amines with CO 2 under ambient conditions

A novel and efficient approach has been developed for the preparation of 2-oxazolidinones through propargylamine–CO 2 coupling reactions employing a Cu( i )-functionalized covalent triazine framework (CTF)/ionic liquid as a recyclable catalytic system.
