Palladium offers various applications in the field of fine chemicals. As one of the most widely used catalytic metals, due to its high activity and selectivity, there are many possibilities for carbon-carbon bond formation in the organic synthesis. This study focused on the condensation reaction between the selected aldehyde or ketone, and 1, 2-Phenylenediamine; as a result, two different Schiff base ligands were prepared. The reaction between palladium(II) acetate and Schiff base ligand, in a molar ratio of 1:1, resulted in the formation of palladium(II) Schiff base complexes PdL¹ and PdL² (L¹ = N-2-hydroxyacetophenon-N′-2, 4-dihydroxbenzaldehyde-1,2 phenylenediimine, and L² = N-2-hydroxyacetophenon-N′-2-hydroxynaphthaldehyde-1,2 phenylenediimine), as identified by elemental analysis, FT-IR, UV–Vis and ¹H NMR spectroscopies. The X-ray analysis of PdL² also showed that the Schiff base acted as …
