E. Rizzi et al., A MASS-SPECTROMETRIC INVESTIGATION ON SOME 3-[2-(NITROXY)ALKYL]-2H-1,3-BENZOXAZIN-4-(3H)-ONE DERIVATIVES, Organic mass spectrometry, 29(10), 1994, pp. 533-539
The electron ionization mass spectrometric behaviour of ten 3-[2-(nitr
oxy)alkyl]-2H-1,3-benzoxazin-4-(3H)-one derivatives has been studied b
y means of metastable ion studies. By mass-analysed ion kinetic energy
spectrometry of the related molecular ions, clear differences have be
en evidenced between the 5-methyl derivative and the other compounds,
consisting of a highly favoured loss of NO2 radical. The same methodol
ogy has allowed easy characterization of isomeric compounds.
