Abstract: A new catalyst system for the Heck reaction consisting of PdCl₂ and 2,6-bis(1,2,4-diazaphosphol-1-yl)pyridine as a ligand is proposed. This system is efficient for the coupling of styrene with aryl bromides (K₃PO₄, DMA, 130 °C) at 0.1 mol% catalyst loading.

Keywords: palladium complexes, coupling, Heck reaction, nitrogen phosphorus heterocycles, 2,6-bis(1,2,4-diazaphosphol-1-yl)pyridine, stilbenes, bromoarenes.
