In the presence of a simple combined catalyst of a tungstate monomer (TBA2WO4, TBA: tetra-n-butylammonium) and rhodium acetate (Rh2(OAc)4), hydrosilylation of various types of substances including ketone, aldehyde, carbon dioxide, alkene, nitrile, and furan derivatives efficiently proceeded, affording the corresponding hydrosilylation products in moderate to high yields (≥63% yields). In addition, the present system was also applicable to the one-pot reduction of benzamide to benzylamine (95% yield).
在钨酸盐单体(TBA2WO4,TBA:四正丁基铵)和乙酸铑(Rh2(OAc)4)的简单组合催化剂存在下,酮、醛、二氧化碳、烯烃、腈和呋喃衍生物等各种类型的物质高效进行氢硅烷化反应,以中等至高产率(≥63%产率)得到相应的氢硅烷化产物。此外,该体系还可用于苯甲酰胺一步还原为苄胺(产率95%)。
