  一种N-甲氧甲基胺类化合物的制备方法

  摘要：

  本发明提供了一种N‑甲氧甲基胺类化合物的制备方法，具体是以氧气或空气为氧源，以甲醇为溶剂，在催化剂作用下，甲醇经过选择性氧化生成甲醛，甲醛与胺发生亲核反应进一步与甲醇缩合，得到N‑甲氧甲基胺类化合物。该方法原料利用率高，催化剂廉价易得，易回收、可循环使用，且易与产品分离。得到的产品性能优异，易分离、提纯，纯度高。此技术路线对于缓解甲醇产能过剩，为甲醇下游产品的开发，具有重要的意义。

  Simple and efficient methods have been developed to obtain cyanomethylamines and azidomethylamines using reactions of methoxymethylamines with TMSCN and TMSN3, respectively. In the case of dimethylformamide dimethylacetal, only one MeO group was substituted with CN, and an unexpected direction of the subsequent azidation was found. Adducts of azidomethylamines with DMAD were studied, and the base-catalyzed isomerization of symmetric triazoles into non-symmetric ones was revealed.

  Three-component condensation of piperazine with formaldehyde and aliphatic alcohols was employed for elucidating the possibility to synthesize N,N'-bis(alkyloxymethyl)piperazines. The structure of the resulting compounds was identified by 1H NMR spectroscopy. The antimicrobial properties of these compounds were examined with respect to microorganisms that infect cooling lubricants and lubricant oils.
