Beitrag zur Massenspektrometrie substituierter α, ω‐Alkandiamine. 29. Mitteilung über massenspektrometrische Untersuchungen

Contribution to the mass spectrometry of substituted α,ω‐alkane diamines The main mass spectral fragmentation pattern of compounds of types 1 to 4 is discussed. After loss of C 6 H 5 · CH 2 · from the molecular ion the acid correspondin to the N , N ‐disubstituted residue is splitted off. The mechanism of this fragmentation reaction depends on the member of CH 2 ‐groups between the two nitrogen atoms ( Schemes 1 and 3 ) and on the substitution pattern of both nitrogens ( Scheme 2 ).
