Rezumat

The novel N-(methylene-2-pyridine)-N,N-bis(diethoxyphosphorylmethyl)amine ligand (L) was obtained through a double Kabachnik-Fields reaction, starting from 2-aminomethyl pyridine (2-picolylamine). In the perspective of developing new catalysts for clean water mediated reactions, a new palladium(II) coordination compound [Pd(L)2Cl2] based on the L ligand, has been synthetized and comprehensively characterized by spectroscopic methods (1H NMR, UV-Vis), ESI mass spectrometry and X-ray crystallography. Figure 1. Scheme of the synthesis of the complex [Pd(L)2Cl2] from ligand L. The [Pd (L)2Cl2] complex crystallizes in the triclinic centrosymmetric space group P-1. The palladium has a square planar coordination sphere provided by two nitrogen and two chlorine atoms in a trans arrangement. The pyridinic rings are situated perpendicular to the plane formed by the central metal and its coordination sphere.
