%X &#945;-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 &#946; cleavage to a carbonyl group, i.e. see diagram in paperCyclic &#945;-dicarbonyl parent negative ions may also eliminate molecules of carbon monoxide, for example the fragmentations M- &#8594; [M-(R + CO)]- M- &#8594;[M - (R-2CO)]- and M- &#8594; [M-2CO]- occur in a number of cases.
