  catalytic direct amination of long‐chain diols, derived from plant oils. High conversion was achieved with good selectivity, with the amount of nitrile impurities formed suppressed to a low level. From the lignocellulose‐based 5‐hydroxymethylfurfural (5‐HMF), or from bis(hydroxymethyl)furan, 2,5‐bis(aminomethyl)furan (BAMF) was generated. 5‐HMF was converted in a one‐pot, one‐step direct amination and reductive

  通过全催化途径，通过衍生自植物油的长链二醇的催化直接胺化来制备长链二胺。以良好的选择性实现了高转化率，并且将形成的腈杂质的量抑制到较低的水平。从木质纤维素基的5-羟甲基糠醛（5-HMF）或双（羟甲基）呋喃中生成了2,5-双（氨基甲基）呋喃（BAMF）。使用氨将5-HMF一步一步转化为直接胺化和还原胺化反应。在两种情况下，反应都非常有效地进行。在组合胺化和还原胺化中，H 2浓度是一个速率限制因素。降低H 2的分压也大大缩短了所需的反应时间。长链二胺与长链二酸的缩聚反应产生了更高分子量的聚酰胺，这说明了通过这种合成方法获得的二胺作为单体的质量。
