- Abstract
The mass spectral behaviour of tetraacetyl spermine ( 2) has been investigated. The fragmentation reactions are characterized by the neighbouring group participation of the amide nitrogen atoms. Only a few reactions can be explained by usual pathways (α-cleavage, onium reactions). Most of the fragment-ions are formed by neighbouring group participation: [ M-COCH3]+-Ion., Breakdown of one of the two 1,3-diaminopropan moieties: m/e 242, 256, 268. This type of fragmentation is characteristic for all acetylated 1,3-diaminopropan-derivatives e.g. triacetylspermidine., Expulsion of a neutral amine: m/e 169., SNi-type reactions, by which cyclic ions are formed: m/e 100.
