Continuous reductive amination of aldehydes with nitroarenes over a Pd–Pt–Fe3O4 catalyst was performed. We used NH3BH3 as not only a hydrogen source for nitro reduction, but also a reductant for imine reduction. Secondary aromatic amines were obtained in the continuous flow reaction in good to excellent yields.

磁性催化剂在连续流系统中的简单可逆固定:超快还原硝基芳烃并随后使用氨硼烷进行还原胺化

在Pd–Pt–Fe 3 O 4催化剂上用硝基芳烃进行醛的连续还原胺化。我们不仅将NH 3 BH 3用作硝基还原的氢源,还将其用作亚胺还原的还原剂。在连续流动反应中以良好至优异的产率获得了仲芳族胺。
