Abstract
Abstract Reactions of 1-ethyl-2-phenylimidazole (Hepim) with lithium tetrachloropalladate(II) and palladium(II) acetate give dichlorobis (1-ethyl-2-phenylimidazole, 3-N) palladium (II) and a new cyclopalladated binuclear complex, di-μ-acetato-bis[2-(1′-ethyl-2′-imidazolyl)phenyl, 1-C, 3′-N]dipalladium(II), respectively. The latter complex is readily converted by a metathetical reaction with sodium chloride into a chloro-bridged analogue, [{PdCl(epim)}2]. The chloro-bridged complex reacts with 4-picoline, tertiary phosphines, thallium(I) acetylacetonate, sodium diethyldithiocarbamate, and 2,2′-bipyridyl to give the corresponding mononuclear cyclopalladated complexes. All the complexes prepared in this study are characterized by means of IR, 1H-NMR, and mass spectroscopies.
