Convenient synthesis of phosphinecarboxamidein by hydrophosphination of isocyanates (and isothiocyanates) was achieved without catalyst and solvent. This system shows shorter reaction time, high yield, and good functional group tolerance.

Catalytic activation of carbon dioxide as a C1 building block under ambient pressure was performed by using a commercially available oxovanadium(v) catalyst for the synthesis of ureas.

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.
