Oxovanadium(V)-Catalyzed Synthesis of Ureas from Disilylamines and Carbon Dioxide under Ambient Pressure.

Here, a commercially available easy-to-handle oxovanadium(V) compound is demonstrated to serve as an efficient catalyst for the synthesis of ureas from disilylamines and carbon dioxide under ambient pressure. The catalytic activation of carbon dioxide proceeds without any additives, demonstrating a broad substrate scope and easy scalability to validate this catalytic activation of carbon dioxide. This catalytic system can be applied to the synthesis of unsymmetric ureas and chiral urea with retention of chirality.
