The EI mass spectra of 13 phorsphorus-containing compounds were reported. The EI spectra of these compounds are characterized by cycle opening cleavage and rearrangement under electron impact conditions. Some rearrangement processes were reported in detail. The substituent effects on fragmentation mechanism of molecular ions were also discussed.
- phorsphoros-containing compound,
- hetero-cyclic compound,
- fragmentation mechanism,
- electron ionization mass spectrometry
