摘要：

Under electron‐impact, N‐alkyl trifluoracetamides exhibit peaks due to [CF3]+ and [M  CF3]+. Ions corresponding to [COCF3]+ are absent. The base peak in many straight chain derivatives occurs at m/e 126 due to alkyl radical loss from the molecular ion; the mass of this ion rising to m/e 140 in the α‐substituted N‐sec‐butyltrifluoracetamide and to m/e 154 in the tert‐butyl derivative. High resolution measurements on a number of peaks indicate that they originate by loss of HF from other fragment ions. Copyright © 1969 John Wiley & Sons, Ltd.
