A new tetradentate N2O2 Schiff base ligand was successfully synthesized via
condensation reaction using primary amine, 1,2-diaminopropane with carbonyl
compound, 2-hydroxy-4-methylacetophenone. The corresponding palladium(II)
complex was then prepared using the synthesized ligand with palladium(II) acetate in
1:1 molar ratio. The synthesized compounds were successfully characterized by FTIR
spectroscopy, NMR spectroscopy, CHN elemental analyses and UV-Vis spectroscopy.
The complex obtained was subjected to the Mizoroki-Heck reaction of 1-bromo-4-
nitrobenzene with methyl acrylate in the presence of N,N-Dimethylacetamide (DMA)
as solvent. Several parameters have been observed such as different type of bases
(sodium acetate, sodium carbonate and sodium bicarbonate), different temperature
(100 °C and 120 °C) and different of catalyst loadings (0.25 mmol%, 0.50 mmol%
and 1.0 mmol%) to give the optimum percentage of catalytic conversion.
