The syntheses, physico-chemical and spectroscopic characterization of ovan-type Schiff-base ligands (L1, L2) and their novel mononuclear Pd(II) complexes (PdL1, PdL2) are reported herein. Elemental analysis, FT-IR,1H NMR as well as magnetic susceptibility measurements characterised the compounds. The catalytic potential of the Pd(II) complexes for Heck coupling reaction were investigated and monitored using GC. It was observed that both Pd(II) complexes displayed properties of good catalysts for the reaction, indicated by 100% conversion of the starting materials to the subtituted alkene product after 6 hours of reaction time at 100°C in inert conditions. The catalytic activity was compared with the reaction without Pd(II) complexes.
Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.002 Å; R factor = 0.029; wR factor = 0.081; data-to-parameter ratio = 31.2.In the title compound, [Pd(C 15 H 13 FNO 2 ) 2 ], the Pd II atom is tetracoordinated by two N atoms and two O atoms from the two 2-[(4-fluorobenzyl)iminomethyl]-6-methoxyphenoxy ligands, forming a square-planar geometry. The two N atoms and the two O atoms around the Pd II atom are trans to each other. The dihedral angle between the two fluoro-substituted benzene rings is 39. 03 (6) . The molecular structure is stabilized by an intramolecular C-HÁ Á ÁO hydrogen bond. In the crystal, weak intermolecular C-HÁ Á Á interactions occur.
