Rather than CH or CC bonds, Pr + activates CF bonds in the gas phase in a variety of aliphatic and aromatic fluorocarbons; PrF + and PrO + react analogously. This first general example of preferential CF bond activation in the gas phase allows interesting conclusions to be drawn regarding the importance of 4f electrons for the reactivity of isolated lanthanide species. The existence of neutral PrF and PrF 2 in the gas phase was also proven by neutralization–reionization mass spectrometry (NRMS).
