Polystyrene as polymer support has various requirements of catalysts for different chemical reactions due to its accessibility, mechanical robustness, product selectivity, chemical inertness, and facile functionalization. This study focuses on the synthesis of polystyrene-supported palladium(II)-hydrazone complex where the hydrazone ligand with an electron donating group (-CH3) acting as the catalyst in Heck reaction. The first step began with aldehyde functionalization of chloromethylated polystyrene to form PS-CHO. This was then followed by the reaction of PS-CHO with p-toluic hydrazide to form a polystyrene-supported hydrazone ligand (PS-H(CH3)), which was then reacted with palladium(II) chloride to form polystyrene-supported palladium(II) hydrazone catalyst, PS-Pd(CH3). The successfully synthesized PS-Pd(CH3) catalyst was characterized using FTIR, PXRD, FESEM-EDX and AAS. The catalytic performance of PS-Pd(CH3) was tested using Heck reaction between 1-bromo-4-nitrobenzene and methyl acrylate. The percent conversion of reactant to product was determined using GC-FID, where the optimum conversion rate was 99.84 with 1.0 mmol catalyst loading, K2CO3 as base and DMA as solvent at 165 °C within a 60-minute reaction time. © 2021, Malaysian Society of Analytical Sciences.
