Reactions of palladium(II) chloride with monoiminoacenaphthenones

Abstract

When PdCl2 reacts with [2,6-diisopropylphenyl]iminoacenaphthenone (dpp-mian) in dichloromethane, the compound 2[Pd(dpp-mian)Cl2]*[Pd(dpp-mian)2Cl2] (1) is formed. It contains two structural units: [Pd(dpp-mian)Cl2], in which dpp-mian is coordinated to Pd(II) in a bidentate-chelate manner by nitrogen and oxygen atoms, and [Pd(dpp-mian)2Cl2], in which two dpp-mian molecules are bonded to palladium only through a nitrogen atom. On the other hand, when PdCl2 interacts with [4-methoxyphenyl]iminoacenaphthenone (4-MeOPh-mian) in dichloromethane, a rearrangement of the ligand structure occurs, followed by the formation of the previously described in the literature complex of Pd(II) with 1,2-bis-[4-methoxyphenyl ]iminoacenaphthene (4-MeOPh-bian) of the composition [Pd(4-MeOPh-bian)Cl2] (2). Compound 1 was obtained for the first time and characterized by X-ray diffraction, as well as by X-ray diffraction, elemental analysis, IR spectroscopy and cyclic voltammetry.
