Gas-phase activation energies have been estimated for the dissociation of one and two phosphines from the cationic ruthenium complex [(η5-indenyl)Ru(HPPh2)3]+ (1) by the combined techniques of ES introduction and Fourier transform ion cyclotron resonance (FTICR) mass spectrometry (MS). These values are 16.6 ± 2.3 and 34.6 ± 2.3 kcal mol-1, respectively.
