Abstract
N-Substituted piperidines with R = CH2OCH3, (CH2)4COCH2, CH3COOC2H5, (CH2)2N(CH3)2, (CH2)2N(C2H5)2, N=0, CH3, H, COOC2H5, and OH were investigated by mass spectrometry. The ratios of the intensities of the peaks and the behavior of the amine fragments with exocyclic double bonds attached to the quaternary nitrogen atom that are formed from the molecular ion by detachment of a radical from the C2 atom and from the substituent attached to the nitrogen atom were studied. It is shown that the ratios of the intensities of the peaks of the amine fragments are determined both by the type of substituent and the energy of the ionizing electrons.
