The N‐alkylation of amines or ammonia with alcohols is a valuable route for the synthesis of N‐alkyl amines. However, as a potentially clean and economic choice for N‐alkyl amine synthesis, non‐noble metal catalysts with high activity and good selectivity are rarely reported. Normally, they are severely limited due to low activity and poor generality. Herein, a simple NiCuFeOx catalyst was designed
胺或氨与醇的N-烷基化是合成N-烷基胺的一条有价值的途径。但是,作为N-烷基胺合成的潜在清洁和经济选择,极少报道具有高活性和良好选择性的非贵金属催化剂。通常,由于活动量低和通用性差,它们受到严格限制。这里,简单的NiCuFeO x设计并制备了用于将氨或胺与醇或伯胺进行N-烷基化的催化剂。在没有有机配体和碱的情况下,成功合成了具有各种结构的N-烷基胺,产率中等至优异。通常,伯胺可以有效地转化为仲胺和N-杂环化合物,仲胺可以被N-烷基化以合成叔胺。请注意,伯氨和仲胺可以通过氨和醇的一锅法反应生成。除了优异的催化性能外,催化剂本身还具有出色的优越性,即对空气和湿气稳定。而且,
