4, Cl 5). 0.05–2.0 mol % of the species 3 acts as a pre‐catalyst for the conversion of aryl and alkyl silylamines under CO2 (2–3 atm) to give the corresponding ureas in 70–99 % yields. A proposed mechanism is supported by experimental and computational data.
铟化合物在(N(森达3)2)2 Cl⋅THF(2)和在(N(森达3)2)氯2 ⋅(THF)Ñ(3)显示出与CO反应2,得到[(箱3的Si)2 N)INX(μ-OSiMe 3)] 2(X = N(森达3)2 4,氯5)。0.05–2.0 mol%的物种3充当在CO 2下转化芳基和烷基甲硅烷基胺的预催化剂(2-3 atm),以70-99%的产率得到相应的尿素。实验和计算数据支持了所提出的机制。
