Abstract

The syntheses, physico-chemical and spectroscopic characterization of salicylaldimine-type Schiff-base ligands (Hapbam, HapFbam) and their novel mononuclear Pd(II) complexes (HapbamPd, HapFbamPd) are reported herein. The compounds were characterized by elemental analysis, FT-IR, 1H NMR as well as magnetic susceptibility measurements. X-ray crystallography investigation of HapbamPd revealed that the Schiff bases behave as singly charged bidentate ligands, coordinating to the palladium centre in the ratio of ligand:metal of 2:1. The geometry of the palladium centre was a perfect square planar. The catalytic potential of the Pd(II) complexes for Suzuki 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 more than 90% conversion of the starting materials to the biphenyl product after 12 hours of reaction time at 100°C in inert conditions. The catalytic activity was compared with that of commercially available palladium(II) acetate.
