with various derivatives (e.g., heptafluorobutyramide, pentafluorobenzamide, and pentafluorobenzylidine) of some clinically important primary and secondary amines. Generally the order of electron-capture sensitivity for primary amines was: pentafluorobenzamide > pentafluorobenzylidine > heptafluorobutyramide, and for pentafluorobenzamides the primary amines were greater than secondary amines.

使用一些临床上重要的伯胺和仲胺的各种衍生物(例如,七氟丁酰胺,五氟苯甲酰胺和五氟苄啶)进行了比较电子捕获敏感性研究。通常,对伯胺的电子捕获敏感性的顺序为:五氟苯甲酰胺>五氟苄啶>七氟丁酰胺,对于五氟苯甲酰胺,伯胺大于仲胺。五氟苯甲酰胺和五氟苄啶中的C = O或C = N基团的还原分别导致反应减弱。通常,灵敏度的顺序是相同的,但是使用detector探测器的响应要比使用镍63探测器的响应大10-20倍。数据符合以下理论:电子不足的系统对于良好的电子捕获响应必不可少,并且该响应也对胺的结构敏感。结果进一步阐明了电子捕获机理,并为选择用于确定特定胺的衍生剂提供了一种更为合理的方法。
