The resulting Schiff bases were utilized as bidentate ligands, coordinating via imine nitrogen and phenolate oxygen atoms, to stabilize palladium ions. Aryl substituents on imine nitrogen allowed for fine tuning of the stereoelectronic properties of the Schiff bases. The catalytic activity of the selected palladium complexes was investigated in the Suzuki cross-coupling reaction of a series of aryl halides with boronic acids in H2O/EtOH (1:1). Out of four complexes investigated in the cross-coupling reactions, Pd(L-8)(2), bearing a methoxy substituent on aryl imine, showed the highest activity at low catalyst loading. The scope of the reaction was also investigated with 26 samples.en10.1016/j.mcat.2021.111528info:eu-repo/semantics/closedAccessSchiff BasePyridoxal-5-PhosphateHomogeneous Palladium CatalystCarbon-Carbon Cross CouplingArticle505Q2WOS:0006378207000062-s2.0-85102991180Q2
