[reaction: see text] A simple, selective, rapid, and efficient procedure for the synthesis of secondary amines from the reductive alkylation of either aliphatic or aromatic nitro compounds and the corresponding amines is reported. Ammonium formate is used as the hydrogen source and Pd/C as the hydrogen transfer catalyst. The reaction is carried out at room temperature. The rate differences for the preferential
[反应:见正文]报告了一种简单,选择性,快速和有效的方法,该方法由脂肪族或芳香族
硝基化合物与相应的胺的还原烷基化反应合成仲胺。
甲酸铵用作氢源,Pd / C用作氢转移催化剂。反应在室温下进行。相对于第三产品优先形成第二产品的速率差异是由于空间和电子因素造成的。
