摘　　要：本文从对氯硝基苯和对硝基苯胺出发,经过两步反应合成了三偶氮类光导材料的重要中间体4,4′,4″-三氨基三 苯胺,其中第一反应采用KF/季铵盐催化法,收率48.4％,第二步反应采用钯碳催化加氢法,收率91.4％。4,4', 4'-Triaminotriphenylamine, a key intermediate in the synthesis of triazo pigments, was prepared from p-nitroaniline and p-nitrochlorobenzene by a two-step reaction. The reaction was catalyzed by KF/Tetramethylammonium chloride with a yield of 48.4% in the first step of the reaction. The second step was a catalytic hydrogenation reaction, using Pd/C as a catalyst with a yield of 91.4%.
