    • PURPOSE: A method for reducing a nitro compound into an amine compound by using an indium metal wire is provided, to prevent the conglomeration of indium metal and to allow the reduction reaction to be carried out under a milder condition. CONSTITUTION: The method comprises the step of reducing a nitro compound represented by the formula 1 into an amine compound represented by the formula 2 by using an indium metal wire in an aqueous solution, wherein R is an aliphatic or aromatic compound. Preferably the reaction is carried out at a temperature of 20-25 deg.C; and the amount of the indium metal is 1.5-2.0 equivalences per a nitro group. Optionally the reaction is carried out in the presence of HCl or HBr which is added to make the pH of the reaction mixture be 1-2.
    • 目的:提供通过使用铟金属线将硝基化合物还原成胺化合物的方法,以防止铟金属的聚集并允许在较温和的条件下进行还原反应。 构成:该方法包括通过在水溶液中使用铟金属线将式1所示的硝基化合物还原成由式2表示的胺化合物的步骤,其中R是脂族或芳族化合物。 反应优选在20-25℃的温度下进行; 并且铟金属的量相对于硝基为1.5-2.0当量。 任选地,反应在HCl或HBr的存在下进行,其加入以使反应混合物的pH为1-2。
