Electron impact ionization mass spectra of some substituted dipyrido[1,2-a 4,3-d]pyrimidinones /
The electron impact ionization mass spectra of dipyrido [1,2-a:4,3-d] pyrimidinones are strongly influenced by the degree of aromaticity of the fused rings. The molecular ions of the compounds are fairly stable. The main routes of fragmentation involve formation of the [M - H]+ ion and loss of subst...

| Tartalmi kivonat: | The electron impact ionization mass spectra of dipyrido [1,2-a:4,3-d] pyrimidinones are strongly influenced by the degree of aromaticity of the fused rings. The molecular ions of the compounds are fairly stable. The main routes of fragmentation involve formation of the [M - H]+ ion and loss of substituents, H2CN., CO and alkyl radicals. |
