Homoleptic lanthanide complex Y[N(TMS)2]3 is an efficient homogeneous catalyst for the hydroboration reduction of secondary amides and tertiary amides to corresponding amines. A series of amides containing different functional groups such as cyano, nitro, and vinyl groups were found to be well-tolerated. This transformation has also been nicely applied to the synthesis of indoles and piribedil. Detailed
均一的镧系元素络合物Y [N(TMS)2] 3是一种高效的均相催化剂,可用于将硼化的仲酰胺和叔酰胺还原为相应的胺。发现一系列含有不同官能团如氰基,硝基和乙烯基的酰胺具有良好的耐受性。该转化也已经很好地应用于吲哚和吡哌贝地的合成。详细的同位素标记实验,对照实验和动力学研究为阐明反应机理提供了累积的证据。
