An easily synthesized ruthenium(II) complex was developed for the direct reductive amination of both aldehydes and ketones with H₂ and ammonia. The intramolecular carboxylate‐assisted hydrogenation fashion was found compatible with the amination between carbonyl substrates and ammonia, enabling a high selectivity toward primary amines. Varied primary amines were obtained with a turnover numbers (TON) up to 376.

易于合成的Ru催化剂可有效地将羰基化合物和氨转化为伯胺

开发了一种易于合成的钌（II）络合物，用于将醛和酮与H ₂和氨直接还原胺化。发现分子内羧酸盐辅助的氢化方式与羰基底物和氨之间的胺化相容，从而对伯胺具有很高的选择性。获得了高达376的周转率（TON）的各种伯胺。
