On the electron impact induced hydroxyl loss fromo-nitrostyrene
摘要:
AbstractUnimolecular hydroxyl (OD˙) loss from 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 HNC from the [M—hydroxyl]+ ion.
