Massenspektrometrische untersuchung organischer stickstoffverbindungen - XVI: Elektronenstossinduzierte fragmentierungen von α-pyridiyl-ω-phenylalkanonen und α-phenyl-ω-pyridylalkanen

The electron impact induced fragmentations of twelve pyridine derivatives are discussed. The fragmentation pattern of these compounds is strongly influenced by the number of methylene groups as well as the position of substitution in the pyridine nucleus. By means of mass spectrometry a differentiation between the 2-pyridyl and the 4-pyridyl derivatives is possible and this fact could be important with respect to an analytical identification of the compounds.
