•Newly synthesized 1,2-bis(arylimino)acenaphthylenylpalladium chlorides.•Characterization including single crystal X-ray molecular structures.•The Heck reaction and high activity.•Highly thermo-stable palladium complex catalyst.
A series of 4,5-bis(arylimino)pyrenylidenylpalladium(II) chloride complexes (C1–C4) were synthesized and characterized by FT-IR and NMR spectroscopy, elemental analysis as well as by single crystal X-ray diffraction for the representative complexes C1 and C3, which revealed a square planar geometry at the palladium center. All palladium complexes exhibited high activity for the Heck cross-coupling reaction, which were effective when conducted in various solvents. Furthermore, the in-situ mixture of palladium dichloride and the ligand (L1) provided an effective catalytic system for the Heck-reaction.
