On the Electron Impact Induced Hydroxyl Loss from o-Nitrostyrene

Article abstract of DOI:10.1002/oms.1210181214

Unimolecular hydroxyl (OD^.) loss form regio- and stereo-specifically labelled o-nitrostyrenes 1a, 1c and 1d results in the formation of an ion which upon collisional activation gives identical mass spectra.Suggestions are made which aim at explaining: (i) the loss of stereochemical integrity of the diastereotopic methylene hydrogens in the course of hydroxyl elimination; and (ii) to account for the collision induced losses of CO and HCN from the (1+) ion.
