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.
在此,一种市售的易于操作的氧钒(V)化合物被证明可作为一种高效催化剂,用于在常压下由二硅胺和二氧化碳合成脲。二氧化碳的催化活化无需任何添加剂即可进行,展示了广泛的底物范围且易于扩大规模以验证这种二氧化碳的催化活化。该催化体系可应用于不对称脲和手性脲的合成,且手性得以保留。
