  • Title: (E)-4-alkoxycarbonylalkylthiochalcones: differentiation of isomeric derivatives by electron ionization mass spectrometry.
    Author: Nowakowska Z, Pankiewicz R.
    Journal: Rapid Commun Mass Spectrom; 2008 Aug; 22(15):2301-6. PubMed ID: 18613297.
    Abstract:
    The principal fragmentation pathways of the molecular ions of 18 new (E)-4-alkoxycarbonylalkylthiochalcones have been investigated. It has been shown that the data derived from electron ionization mass spectra (the relative abundance of the fragment ions and values of coefficients micro) can be used to differentiate the isomers. The fragmentation rules deduced here could help in the characterization of other chalcones of these types.
