摘要: A series of palladium(II) complexes with different Schiff base ligands were synthesized. Phosphine-free bases derived from benzaldehyde formed cyclometallated complexes, which are air- and moisture-stable have dimeric, acetate-bridged structures. Monomeric, obtained phosphine-containing bases. The chelating iminophosphine coordinate to palladium via the phosphorus nitrogen atom. These applied as catalysts for Heck reaction bromobenzene styrene. Excellent yields transstilbene catalyst loadings 0.01 mol%. influence water on performance was investigated.
