摘要
研究了以2(3H)-苯并唑酮为端基、具有酰脲结构的非环多醚化合物的质谱。各化合物呈现出相似的质谱峰。M+1离子可以进行McLafferty重排,其碎片离子(m/z207)也可以进行McLafferty重排.此外,碎片离子(m/z207)的McLafferty重排产物(m/z177)又进行了新的甲基重排反应。
The mass spectra of ureide-type noncyclic polyethers with 2(3H)-benzoxazolone as end groups were studies. These compounds exhibited similiar mass spectra properties.McLafferty rearrangements occourded in M+1 ion to give the fragment ion(m/z 207)which took further McLafferty rearrangements to give the fragment ions (177). Moreover,the fragment ion (m/z 177)took a new methyl rearrangement.
