摘　　要：邻硝基甲苯在甲醇、乙酸和硫酸混合溶液中,在Pt/C的催化下发生氢化和Bamberger重排生成2-甲基-4-甲氧基苯胺.后者在Pd/C的存在下以苯酚为反应介质与环已酮缩合生成2-甲基-4-甲氧基苯基苯胺,反应总产率63.0%.文中给出了产物与中间产物的核磁共振氢谱和质谱,同时讨论了影响反应的因素.Using Pt/C as a catalyst, the hydrogenation and Bamberger rearrangement of o-nitrotoluene was carried out in a solution consisting of methanol, sulfuric acid and acetic acid, to afford 2-methyl-4-methoxyaniline. The intermediate product was further reacted with cyclohexanone in the presence of Pd/C in phenol to form N-phenyl-2-methyl-4-methoxyaniline. The total yield is 63%. The product as well as intermediate was determined by H-1 NMR and MS spectra. The factors of affecting the reactions were also discussed.
