  continuous‐flow procedure for direct reductive amination of secondary and primary amines with aromatic and aliphatic aldehydes as well as ketones is reported. The use of hydrogen gas and commercially available Pt/C as a heterogeneous catalyst is a key. In addition to exhibiting an excellent functional group tolerance, this method allows the fast formation of C−N bonds without production of any hazardous

  据报道，一般的连续流方法可直接将仲胺和伯胺与芳香族和脂肪族醛以及酮进行直接还原胺化。关键是要使用氢气和可商购的Pt / C作为非均相催化剂。除了具有出色的官能团耐受性外，该方法还可以快速形成C-N键，而不会产生任何危险的化学废料。还描述了在合成关键中间体以生产活性药物成分方面的应用（Donepezil和Arformoterol / Tamsulosin）。
