Sažetak
Intense rearrangement processes involving migrations of hydrogen atoms and the phenyl group were observed in the electron impact induced fragmentation of 1-benzyl-3, 3-dimethyldiaziridine. The following ions are observed: (i) m/z 146: a two step fragmentation involving hydrogen transfer followed by loss of NH2 ; (ii) m/z 119: C-N1 bond fission followed by a 1-4 phenyl shift and loss of CH3N2 ; (iii) m/z 106: a process involving reciprocal hydrogen migration between the methyl and benzylic methylene groups ; (iv) m/z 58: hydrogen transfer from benzylic methylene and subsequent loss of PhCHN. The origin of these ions has been confirmed by measurements of metastable transitions in 1-benzyl-3, 3-dimethyldiaziridine, and on specifically deuterated and substituted diaziridines. The structure of the ions at m/z 119 and m/z 106 has been deduced by means of collisional activation spectrometry.
