Synthesis of platinum and palladium complexes with bis-(hydroxy imines)

Abstract

The Schiff bases are an important class of compounds well used as ligands in coordination chemistry. The functionalized bis-imines, that represent a specific group of Schiff base, have been studied in our research group both for the evaluation of biological activity, against fungi and cancer, as for organocatalyst. Here the bis-imines 1 and 4 were synthesized in good yields by condensation of hydroxylated benzaldehydes with phenylenediamines. After that they were matched with Platinum and palladium salts providing three metallic complex (2, 3 and 5) that were fully characterized by nuclear magnetic resonance and mass spectrometry with electrospray ionization. Now these complexes are being tested in cross-coupling reactions of Heck and Suzuki.
