A simple and facile to prepare Pd(II) complex containing the pyridyl imine ligand [C5H4N-2-CH3CN-(CH2)3NH2]. Structural characterization and catalytic evaluation in Suzuki–Miyaura C–C couplings

• A Pd(II) complex with a κ3-N,N,N pyridyl imine ligand was readily synthesized in good yields.
• The palladium derivative PdL1 exhibited good to excellent catalytic activities in Suzuki–Miyaura Couplings.
• The structure of complex PdL1 was unequivocally determined by X-ray diffraction techniques.
• Studies in the solid state reveal important non-covalent interactions.

The facile and simple synthesis and structural characterization of a Pd(II) complex derived from the ligand N1-(1-(pyridin-2-yl)ethylidene)propane-1,3-diamine (L1) is described. The Pd(II) species [Pd(L1)Cl][BF4] (PdL1) has been fully characterized and its structure unequivocally determined by single crystal X-ray diffraction techniques. The molecular structure of PdL1 shows the ligand L1 coordinated in a κ3-N,N,N-tridentate fashion thus affording a slightly distorted square planar compound. This species was employed as catalyst in Suzuki–Miyaura couplings affording good to excellent yields. Furthermore, in the solid state this compound exhibited extended hydrogen-bond networks.
