Abstract
α-Dicarbonyl
compounds form stable parent negative ions by capture of low-energy electrons.
The parent negative ions undergo a variety of collision induced dissociations,
the most characteristic being β cleavage to a carbonyl group, i.e. see diagram in paperCyclic α-dicarbonyl parent negative ions may also eliminate
molecules of carbon monoxide, for example the fragmentations M- → [M-(R +
CO)]- M- →[M - (R-2CO)]- and M- → [M-2CO]- occur in a
number of cases.
