Abstract

The present communication deals with the electron impact
studies on ethyl 2,3-dioxobutyrate-2-phenylhydrazones and
related substituted phenylhydrazones containing electron releasing
as well as electron withdrawing substituents on the
phenyl nucleus. The formation of base peaks were greatly
influenced by the nature of substituent in the phenyl nucleus.
Neutral and radical loss from the aromatic subtituents were
also found to depend upon the nature of groups. These
hydra zones undergo thermal isomerisation to azo form which
fragments subsequently to daughter ions in accordance with
the azo structure having very low relative intensity and L
