【Abstract】 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%.更多还原
