On March 29, 2022, Matsutani, Takanari; Aoyama, Kotaro; Moriuchi, Toshiyuki published an article.Electric Literature of 102-07-8 The title of the article was Oxovanadium(V)-Catalyzed Synthesis of Ureas from Disilylamines and Carbon Dioxide under Ambient Pressure. And the article contained the following:
Here, a com. available easy-to-handle oxovanadium(V) compound is demonstrated to serve as an efficient catalyst for the synthesis of ureas RNHC(O)NHR (R = n-hexyl, cyclohexyl, Ph, PhCH2CH2, etc.) from disilylamines RN(SiMe3)2 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 unsym. ureas and chiral urea with retention of chirality. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Electric Literature of 102-07-8
