文摘

The 2-((2-benzylamino)phenyldiazenyl)phenol, H₂OL [where H₂OL = ArOHN = NC₆H₄N(H)CH₂(C₆H₅); Ar = C₆H₅ (for H₂OL¹), p-MeC₆H₄ (for H₂OL²) or p-ClC₆H₄ (for H₂OL³)], ligands were prepared by the reaction of the appropriate 2-((2-hydroxyaryl)azo)anilines with benzyl bromide. The reactions of Na₂PdCl₄ with H₂OL afforded tetranuclear Pd(II) complexes of the composition [Pd(OL)]₄. The ligands bind palladium(II) in a tridentate (N, N, O) fashion. The X-ray structure of [Pd(OL¹)]₄ was determined to confirm the characterization. The newly synthesized [Pd(OL¹)]₄ complex was utilized as a catalyst for the Suzuki and Heck reaction for a variety of substrates.
