    Abstract: The electron ionization (EI) fragmentation of nitro-,-dihalostyrenes depends strongly on the specific halogens present as well as on the position of the nitro group. ,-Difluorostyrenes yielded mainly fluoroacetylene ions as the base peaks and o-nitro-,-dihalostyrene possibly furnished the ion with a structure similar to that of benzo[a]isoxazole (11). The structural identity of the ion was verified by comparing the collision-induced dissociation (CID) spectra of m/z 119 ions from p- and o-nitro-,-difluorostyrene, o-nitro-,-dibromostyrene and compound 11.
