Notes:
Positive-ion chemical ionization mass spectra were measured for simple bifunctional aromatic compounds of the type p-XCH2C6H4CH2Y, where X = NH2, NH(CH3) and N(CH3)2 and Y = OH and OCH3. For each compound, essentially only three peaks of ions, [MH]+, [ MH - XH] + and [MH - YH] +, appeared. The B/E con stant linked-scan spectra showed that the stable non-decomposing [MH]+ had the proton only on the nitrogen-containing functional group. From these data, the relative amounts of total protonation, the ratio of N-and O-protonation and the fraction of fragmenting [MH]+ can be calculated. The ease of protonation (protonation susceptibility) and the reactivity (fragmentation capability) of the respective functional groups are discussed.
