Sulfur ylides 9. Resonance electron capture by molecules of keto-stabilized sulfur ylides containing a phthalimide fragment

Article abstract of DOI:10.1007/bf02494850

The mass spectra of negative ions of keto-stabilized sulfur and phosphorus ylides (obtained from amino acids) and products of their thermal conversion are studied. The most characteristic peaks in the mass spectra of ylides belong to negative molecular ions and to [M - H]^- ions. Peaks of fragment ions in the mass spectra of ylides and products of their thermal conversion coincide both in mass numbers and resonance energies.
