✦ Synopsis
Stereospecific Fragmentations in the Mass Spectra of Cyclohexanediamines and Bis(aminomethyl)cyclohexanes
The mass spectral behaviour, especially loss of NH~3~, of the six isomeric cyclohexanediamines 1‐‐3 (cis and trans each, Scheme 1) as well as of the six isomeric bis(aminomethyl)cyclohexanes 4‐‐6 (cis and trans each, Scheme 6) has been investigated. The cis‐ and trans‐compounds of the 1,2‐isomers 1 and 4 show very similar spectra, because of the ease of ring cleavage at C(1)–‐C(2) and the similar geometrical relations in all ring conformations. The cis‐ and trans‐compounds of both the 1,3‐ and 1,4‐isomers 2, 3, 5 and 6 show striking differences in their mass spectra due to stereospecific elimination of NH~3~ from the molecular ion.
