Nachbargruppeneffekte bei der massenspektrometrischen Fragmentierung: N‐Acetyl‐ω‐Phenylalkylamine . 20. Mitteilung über das massenspektrometrische verhalten von stickstoffverbindung

The mass spectral behaviour of the difunctional alkane N‐acetyl‐4‐phenyl‐butylamine ( 3 ) was investigated. The main fragmentation of compound 3 is caused by the interaction on the two functional groups, which could be shown by comparison of the corresponding monofunctional compounds n ‐butylbenzene ( 4 ) and N‐acetyl‐ n ‐butylamine ( 5 ). On the bases of high resolution data, the analyses of metastable transitions and the comparison of the spectra of some homologs and deuterated analogs of 3 the structures and their genesis of the main fragment i ons were deducted.
