Heterocyclic studies. Part 41. Disproportionation of acridinium compounds and mass spectra of some acridines
Abstract
Deuterium labelling is used to show that disproportionation of 10-methylacridinium iodide involves transfer of a hydride ion from the 9-position of the pseudo-base form of the compound to the 9-position of the 10-methylacridinium ion. Mass spectrometric fragmentations of some acridine and acridan derivatives have been elucidated with the aid of deuterium-labelled compounds.
