Nanoparticles in a Deep Eutectic Solvent: An Efficient and Recyclable Catalytic System for the Synthesis of Primary Carbamates and Monosubstituted Ureas
Superparamagnetic Fe3O4 nanoparticles were used to prepare primary carbamates as well as monosubstituted and N,N‐disubstituted ureas. This efficient phosgene‐free process used urea as an eco‐friendly carbonyl source in the presence of a biocompatible deep eutectic solvent (DES) to provide an inexpensive and attractive route that afforded the products in moderate to excellent yields.
