The Elimination of Masses 27 and 28 from the + Ion of 2-Nitrotoluene

Article abstract of DOI:10.1002/oms.1210190703

The expulsion of neutral fragments of masses 27 and 28 from metastable ⁺ ions derived from 2-nitrotoluene has been observed.The relative abundances of the resulting fragment ions, together with the kinetic energy released in each process, has been compared with similar fragmentations of ⁺ ions derived from other precursor molecules.In this way, the nature of the neutral fragments and the structure of the ⁺ ions from 2-nitrotoluene has been investigated.The most likely structure is the 1,2-benzisoxazolenium cation although the coexistence of other structures cannot be ruled out on the present evidence.
