Abstract: The polyschiff base Pd(Ⅰ)complexes were used as catalysts to hydrogenate aromatic nitrocompounds at room temperature and ordinary pressure. Nitrobenzene was hydrogenated quantitatively,the conversion for most other aromatic nitrocompounds was also up to 90%. The catalyst is stable,For hydrogenation of nitrobenzene after reusing around 80 times,the fast rate of taken-up hydrogen remained 25mL/min.The catalyst reused for 10 times has been proved by XPS to be Pd(Ⅰ)complex.

Key words: poly-schiff base-Pd complex, catalytic hydrogenation, aromatic nitrocompound
