The synthesis and properties of the cationic palladium(II) complexes are described. Dicationic [Pd(PPh3)4](X)2 (X = BF4-, PF6-) and [Pd(P(OPh)3)4](PF6)2 have been prepared by the reaction of Pd(PPh3)4 with CPh3X (X = BF4-, PF6-). A pentacoordinated Pd(II) complex of the heterocyclic ligand 1,10-phenanthroline, [Pd(1,10-phen)2(PPh3)](X)2) was obtained from the reaction of [Pd(PPh3)4](X)2 with 1,10-phen. Monocationic [Pd(CH3COCHCO-R)(PPh3)2](X) (R = Me, OMe) has been isolated from the reaction of Pd(PPh3)4 with CPh3X in the presence of acetylacetone or methyl acetoacetate. Likely structures and some features for these new complexes are proposed from 1H NMR and IR spectrometry.
