    The electron-impact-induced fragmentation of acridine (1974)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 8 (1974), S. 95-102

    Notizen: Studies of both high and low resolution spectra, and of metastable decompositions occurring in both the first and second field-free regions of the mass spectrometer have led to a postulated scheme for the fragmentation of acridine under electron-impact. There is no specific loss of label from either [9-2H1]acridine or [4,5-2H2]acridine in any fragmentation, nor is there any total scrambling of label in either molecular ion prior to loss of HCN. There is certainly some degree of scrambling preceding HCN loss from [M]+· at 70 eV, but this does not involve the 9-H to any detectable extent. There is no strong evidence for the acridine molecular ion having the same structure as that of four other C13H9N isomers.

    Electron impact induced alkyl-group fragmentation on the acridine nucleus (1977)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 12 (1977), S. 518-530 
    Details
    ISSN: 0030-493X
    Schlagwort(e): Chemistry ; Analytical Chemistry and Spectroscopy

    Thema: Chemie und Pharmazie
    Notizen: The fragmentation of simple alkyl acridines closely resembles that of the analogous quinoline derivatives. Interaction between the heteroatom and a 4-alkyl substituent dramatically influences the fragmentation pattern with resultant γ-cleavage or rearrangement to the heteroatom and corresponding elimination of an alkene fragment. The fragmentation of the 9-chloroalkylacridines closely resembles that of the acridines with the loss of the clorine atom superposed on the alkylacridine fragmentation. Redistribution of the centre of apparent charge localization occurs for the acridones with a tendency for interaction with the 9-position.

    Notizen: Further examples of the diagnostic vicinal C,H coupling constants of trisubstituted alkenes are reported, and the application of the method confirms the structures of four dimethyl acetylenedicarboxylate adducts.
