Abstract
The mass spectra of 9-aryl(hetaryl)-3,3,6,6-tetramethyldecahydroacridine-1,8-diones have been studied and the basic directions of their dissociative ionization under the influence of electron impact have been elucidated. It has been shown that the decomposition pathways of decahydroacridine-1,8-diones depend on the nature of the substituents at position 10 and is connected with the preferential formation of a pyridinium structure with subsequent retrodiene decomposition of the molecules.
