The preparation of nickel nanoparticles as efficient reductive amination catalysts by pyrolysis of in situ generated Ni‐tartaric acid complex on silica is presented. The resulting stable and reusable Ni‐nanocatalyst enables the synthesis of functionalized and structurally diverse primary benzylic, heterocyclic and aliphatic amines starting from inexpensive and readily available carbonyl compounds and ammonia in presence of molecular hydrogen. Applying this Ni‐based amination protocol, ‐NH2 moiety can be introduced in structurally complex compounds, for example, steroid derivatives and pharmaceuticals.

可重复使用的镍纳米粒子催化的还原胺用于伯胺的选择性合成

本文介绍了通过在二氧化硅上热解原位生成的酒石酸络合物来制备作为高效还原胺化催化剂的镍纳米粒子的方法。所得的稳定且可重复使用的镍纳米催化剂能够在分子氢存在下,从廉价且易于获得的羰基化合物和氨开始,合成功能化且结构多样的伯苄基,杂环和脂肪族胺。应用这种基于镍的胺化方案,可以将-NH 2部分引入结构复杂的化合物中,例如,类固醇衍生物和药物。
