  secondary amines. Further development of the reductive monoalkylation reaction provided conditions that facilitate conversion of a range of different nitro aryls in one-pot to the corresponding secondary benzyl amino aryls in mostly good to excellent yields. This is accomplished by using hydrogen (1 atm) over Pd/C (10%) as reducing agent and benzaldehyde as the benzyl source combined with a stepwise

  当在乙醇中的Pd / C（10％）上用氢气（1 atm）处理硝基官能团还原为相应的伯胺时，发生乙酸乙酯（4-甲氧基-3-硝基苯基）的意外还原性单烷基化反应的范围被调查。在延长的反应时间在乙醇和甲醇中进行反应得到相应的仲胺的显著量，在执行时，同时Ñ丁醇和我-丙醇仅导致形成少量相应的仲胺。还原性单烷基化反应的进一步发展提供了有利于将一锅中的一系列不同硝基芳基转化为相应的仲苄基氨基芳基的条件，其收率大体上以优异的优良率转化。这是通过在Pd / C（10％）上使用氢气（1 atm）作为还原剂，并使用苯甲醛作为苄基源结合逐步反应序列来实现的。该化学反应进一步扩展到取代的苄基氨基芳基的形成。后者产物的产率根据与苯甲醛有关的取代方式而有很大变化。但是，通过改变反应条件，可以提高苄基化产物的产率。

  A range of different nitro aryls were converted in one-pot to the corresponding secondary alkyl amino aryls in good to excellent yields by using aldehydes as alkyl source and hydrogen over Pd/C (10%) as reducing agent. In all examples, but one, the secondary amine was the sole alkylation product isolated. When formaldehyde was used as the alkyl source, substantial amount of the corresponding tertiary
