Some cationic η3-propargylpalladium complexes were prepared upon treatment of the corresponding η1-propargyl- or η1-allenylbis(triphenylphosphine)palladium(II) chloride with Ag[BF4] or Na[BPh4]. The effectiveness of the latter reagent suggests that a η1-propargyl- or η1-allenyl(chloro)palladium complex equilibrates with a cationic η3-propargylpalladium complex with the liberation of a Cl− ligand.

Treatment of eta(1)-allenyl- or eta(1)-propargylpalladium bis(triphenylphosphine) chloride with AgBF4, or NaBPh(4) afforded cationic eta(3)-allenyl/propargylpalladium complexes. The molecular structure and some properties of the eta(3)-allenyl/propargylpalladium were revealed.
