Abstract
Mass spectrometric behaviour of some anthraquinone derivatives has been studied by fast-atom bombardment ionization. For all the compounds under study, a retrosynthetic process, consisting in the cleavage of the NH-CO bond with hydrogen rearrangement, has been detected. This decomposition pathway leads to the formation of the protonated molecule of 1,4-diaminoanthraquinone or to the 1-amino-4,5,8-trihydroxy-anthraquinone, representing the basic synthetic elements of the compounds under investigation.File in questo prodotto:
