• Two allyl-palladium(II) complexes bearing the Trost standard ligand (1), i.e., [(C3H5)Pd(S,S-1)]+CF3SO3 − and [(c-C6H9)Pd(S,S-1)]+BArF− (BArF− = [B((3,5-(CF3)2)C6H3)4]−), are investigated using electrospray ionization (ESI) mass spectrometry. Both species form abundant quasi-molecular ions [(C3H5)Pd(S,S-1)]+ and [(c-C6H9)Pd(S,S-1)]+, respectively. At elevated concentrations of the solutions admitted to the ESI source, significant aggregation to binuclear species is observed, which agrees with recent results from solution chemistry. Consistent with solution-phase studies, the tendency of clustering is much less pronounced for the bulky BArF− counterion compared to the smaller triflate.
