A stable, reusable, and highly active catalyst for liquid phase hydrogenation reaction has been developed by reacting poly(3,6-diamino N-vinylcarbazole) with benzaldehyde to get polymer-anchored Schiff base which was then reacted with bis(benzonitrile)palladium(II)chloride [Pd(PhCN)(2)Cl-2] to get the polymer-anchored complex. The complex was characterized by using scanning electron microscope (SEM), thermogravimetric analysis (TGA), elemental analysis, atomic absorption spectroscopy (AAS), and spectrometric methods like diffuse reflectance spectra of solid (DRS) and Fourier transform infrared spectroscopy (FTIR). The catalytic performance of this catalyst was investigated in hydrogenation of various organic substrates under high-pressure condition. The results showed that the catalyst were highly efficient for hydrogenation reaction and gave excellent yields of products. At the same time, the catalyst was very stable and could be reused for more than five times without noticeable loss of its catalytic activity.
