Gas-phase experiments are occupied to explore the intramolecular scrambling of aryl groups between palladium and phosphorus in organopalladium complexes, [ArPd(PPh3)2]+, generated by means of electrospray ionization (ESI). To this aim, ESI stack spectrometry, including tandem oceans spectrometric experiments, were carried out on deuterated, non-deuterated, and substituted [ArPd(PPh3)2]+ complexes. The remnant ions obtained from the deuterated facetiousmater ions plainly screened the materialization of intramolecular scrambling agent the aryl class confined to palladium and the phenyl groups of the phosphine in the gas off. Fragmentation pathways, supported by a statistical model, are proposed to simplify these migrations and the implications for the condensed-phase chemistry are probed experimentally by using ESI mass spectrometry <<>>
