摘要：

The effects of substituents on the fragmentation of N‐aryl trifluoracetamides has been investigated. The base peak in all ring‐monosubstituted derivatives is the molecular ion. Other important ions arise by loss of CF3 and COCF3 from the molecular ion, and the latter daughter ion fragments further, by loss of the aromatic substituent and by expulsion of small neutral molecules. The effects of substituents on the intensity of these ions is discussed. 1‐Phenylethyl trifluoracetamide exhibits a base peak which is the molecular ion, wheras the corresponding 2‐phenyl derivative has a molecular ion of very low intensity.
