The reactions of the [2-2]-paracyclophane 1 and the [2-2]-metaparacyclopane 2 in the gas phase after protonation by CI(CH4) or CI(I-C4H10) were studied by FT-ICR mass spectrometry. The ions C16H17+ produced in the external ion source of the FT-ICR in

The differences in the gas-phase basicities (GBs) of isomers can be used for a semi-quantitative mixture analysis. For this “gas-phase titration” method, the mixture of isomers is completely protonated in the external ion source of a FT-ion cyclo

The rates of deprotonation, MH+ + B --> M + BH+ (M = 1, 2), and the rates of protonation, M + BH+ --> MH+ + B (M = 2, 3, 4), have been measured by Fourier transform-ion cyclotron resonance (FT-ICR) spectrometry for the increasingly sterically crowded
