The mechanism of NO loss from the molecular ion of nitrobenzene and the fragmentation behaviour of the phenoxy and p-aminophenoxy cations
Abstract
The mass spectra of [1-13C]nitrobenzene and [1-13C]-p-nitroaniline reveal that in the phenoxy and the p-aminophenoxy cations, produced by loss of NO from their molecular ions, positional identity of the oxygen atom is retained in their subsequent fragmentations.
