We developed solvent-free reductiveaminationwithout an externalhydrogensource using iron pentacarbonyl as a reducing agent. Neither a catalyst nor any other additives were employed. Various types of substrates are suitable for the reaction, including those with low reactivity, e.g. benzophenone. Among others, the protocol tolerates bromo-, cyano-, benzyloxy-, pyrimidyl and styryl moieties.

Catalytic reductive reactions are essential for laboratory and industrial-scale organicsynthesis. However, the nowadays trend is the development of new, more and more complicated reducing systems, which hinders the application of such highly efficient approaches in practice. Another way to achieve the highly active systems is enhancing the activity of the earlier developed catalysts with simple structures

Herein we report a transition-metal- and acid-free protocol for the reductive amination of carbonylcompounds with DMF using a substoichiometric amount of NaH2PO2·H2O. A set of various N,N-dimethylamines were obtained in moderate to excellent yields without chromatographic purification. The general trends and limitations of the method with different formamides as sources of dialkyl-fragments were explored
在此,我们报告了一种使用亚化学计量的 NaH 2 PO 2 · H 2 O的 DMF 对羰基化合物进行还原胺化的无过渡金属和无酸方案。无需色谱纯化即可获得出色的收率。探讨了使用不同甲酰胺作为二烷基片段来源的方法的一般趋势和局限性。
