Nanocatalytic Amination: Herein, a reusable heterogeneous N-doped graphene-based manganesenanocatalyst (Mn@NrGO) for selective N-alkylation of amines with alcohols is described. The heterogeneous nature of the catalyst made it easy to separate for long-term performance, and the recycling study revealed that the catalyst was robust and retained its activity after several recycling experiments.

pharmaceuticals such as d-Cloperastine, d-Buclizine, d-Diphendyarmine, d-Modafinil, and d-Adrafinil using CD3OD. In addition, the application of methanol as a C1 source for the preparation of N-methylated products is showcased. Finally, kinetic and mechanisticinvestigations for this Ru-catalyzed transfer hydrogenation and deuteration protocols have been performed.
有机合成和能源技术中甲醇的催化增值对于基础研究和工业应用来说都是有趣且重要的。特别是,它作为氢、氘和甲基源用于选择性还原和氘化反应以及获得N-甲基化产物是非常理想的,并且可以被认为是放大转移氢化和C1化学的潜在方法。在这里,我们报道了均相 Ru-MACHO 配合物催化不同官能化化合物(如酮、醛、炔烃、烯烃、亚胺、偶氮苯和硝基化合物)的转移氢化以及N的脱氧使用甲醇作为负担得起的氢供体和溶剂的氧化物衍生物。这种基于钌的策略已被证明对于合成先进氘标记化合物的氘化过程非常方便,包括克级合成氘代药物,如d-氯哌斯汀、d-布克利嗪、d-苯地亚明、d-莫达非尼和d -Adrafinil 使用 CD 3 OD。此外,还展示了甲醇作为C1源用于制备N-甲基化产物的应用。最后,对这种钌催化的转移氢化和氘化方案进行了动力学和机理研究。
