摘要：

The fragmentations under electron impact of 5‐phenyl‐1,4‐benzodiazepin‐2‐ones are investigated with the aid of high resolution, metastable decompositions and deuterium labeling. Based on our data a mechanism for the formation of the [M – H]+ ion is proposed. It is shown that the [M – CHO]+ ion is probably formed by two different pathways. Data on two minor fragment ions give support to the structure proposed for the [M – CHO]+ ion. Copyright © 1979 John Wiley & Sons, Ltd.
