The synthesis of N‐substituted amines is one of the key transformations in synthetic chemistry and chemical industry, because amines are ubiquitous in the syntheses of agrochemicals, pharmaceuticals, flavorings, fragrances, and advanced materials. In order to realize the clean and economic synthesis of N‐substituted amines, several aspects should be concerned. 1) The application of alkyl halides as alkylation reagents should be replaced by alcohol and alkane; 2) the employment of amines as nitrogen sources can be replaced by nitrobenzene, nitrile and ammonia; 3) the application of environmentally benign and low‐cost starting materials, such as CO₂, HCHO, biomass resources, for the nitrogen‐containing chemicals synthesis should be established; and 4) economic, green and efficient catalyst should be developed for the above transformations. In this account, we describe our results in the clean and economic synthesis of N‐substituted amines with amine, ammonia, nitrobenzene or nitrile as nitrogen sources and alcohol, alkane or CO₂, HCHO, CO, and biomass resources as alkylation or carbonylation reagents.

通过绿色和可再生原料实现经济和可持续的胺化

N-取代胺的合成是合成化学和化学工业中的关键转变之一，因为胺在农用化学品，药物，调味剂，香料和高级材料的合成中无处不在。为了实现N-取代胺的清洁经济合成，应注意几个方面。1）使用烷基卤作为烷基化试剂时，应以醇和烷烃代替；2）使用胺作为氮源可以用硝基苯，腈和氨代替；3）使用环境友好且低成本的原材料，例如CO ₂应当建立用于合成含氮化学品的HCHO，生物量资源；4）为上述转化开发经济，绿色，高效的催化剂。因此，我们描述了以胺，氨，硝基苯或腈为氮源，以醇，烷烃或CO ₂，HCHO，CO和生物质资源为烷基化或羰基化试剂的N-取代胺的清洁经济合成方法的结果。。
