The ?-Bonded Palladium(II) Complexes of 2-Aryl-4,4-dimethyl-2-oxazolines

Article abstract of DOI:10.1246/bcsj.54.1711

Reactions of 2-phenyl-4,4-dimethyl-2-oxazoline with lithium tetrachloropalladate(II) and palladium(II) acetate give dichlorobis(2-phenyl-4,4-dimethyl-2-oxazoline,3-N)palladium(II) and a cyclopalladated binuclear complex, di-μ-acetato-bis<2-(4',4'-dimethyl-2'-oxazolinyl)phenyl,1-C,3'-N>dipalladium(II), respectively.The latter complex is readily converted by a metathetical reaction with lithium chloride into its chloro-bridged analogue.The chloro-bridged complex reacts with triphenylphosphine to give the corresponding mononuclear ?-bonding palladium complex.All the complexes prepared in this study were characterized by means of IR and NMR spectroscopies.
