A simple and facile to prepare Pd(II) complex containing the pyridyl imine ligand [C5H4N-2-CH3C=N-(CH2)(3)NH2]. Structural characterization and catalytic evaluation in Suzuki-Miyaura C-C couplings

摘要

The facile and simple synthesis and structural characterization of a Pd(II) complex derived from the ligand N-1-(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 kappa(3)-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.
