本文报道了六种新的咪唑衍生物的电子轰击质谱,着重讨论了P--C, P--N键的断裂; 产物离子的开环反应;产物离子的H重排反应和失去CO的反应等. 根据高分辨精确质量测量和联动扫描技术, 讨论了化合物的质谱裂解机理.

关键词: 咪唑 P, 质谱法, 精确质量测量, 联动扫描, 电子轰击

The electron impact mass spectra of six new imidazole derivatives are reported with the emphasis on the cleavages of the P--C, P--N bonds,open circle reactions of the products, innermolecular rearrangement reactions and loss of CO reactions. General fragmentation mechanism and mass spectra behaviors have also been discussed by using high resolution precise mass determination and linked scan techniques.

Key words: MASS SPECTROGRAPHY, IMIDAZOLE P, COMBINED SCANNING, ELECTRON BOMBARDMENT
