| Abstract: | 1,4-benzoxazin-2-one derivatives have been researched by electron impact mass spectrometry( EI-MS ). Based on EI-MS spectrum, as well as the structure characterizations of these compounds, some fragmentation rules are obtained. The molecular ion fragments were observedwith different abundance in the mass spectra of al sampleds. The base peak of most 1,4-benzoxazine-2-one derviatives suggested a carbon monoxide eliminaion leading to characteristic 2-methyl-benzoxazole radical cations (M-28). Though, other processes would be competivive with other easier splitting substituents (R), such as acetyl and methyl et al. These compounds showed very weak peak at M-28 with a base peak at M-R or M-R-28, which were formed in a direct splitting of R (M-R) following by the elimination of carbon monoxide (M-R-CO). |
