Cationic organocarbonyl palladium(II) complexes

The carbonylation under normal pressure, at 0°C, of organometallic perchlorato palladium(II) complexes in solution leads to the displacement of the perchlorato group and the formation of a series of cationic organocarbonyl palladium(II) compounds of the general formula CO(C₆F₅)PdL₂]ClO₄, where L₂ are either two tertiary phosphine groups or a nitrogen chelate, such as 2,2′-bipyridine, 1,10-phenanthroline or N,N,N′,N′-tetramethylethylenediamine.
