Vk. Mavrodiev et al., Sulfur ylides - 9. Resonance electron capture by molecules of keto-stabilized sulfur ylides containing a phthalimide fragment, RUSS CHEM B, 48(11), 1999, pp. 2077-2079
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 b
elong 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.
