Mass-spectrometric investigation of isatins

I. N-alkylisatins

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

It is shown that in the mass spectra of N-alkylisatins with a normal C1-C10 chain the intensity of the [M-CO]+- and [M-(2CO)]+. peaks characteristic for isatin and N-methylisatin decreases as the alkyl radical is lengthened, whereas the intensity of the peak formed as a result of successive loss by the molecular ion of a CO group and a portion of the radical as a result of cleavage of the bond at the α-carbon atom increases. Fragments due to α,β,γ... cleavages, both without migration and with migration of the hydrogen atoms, appear in the spectra of N-alkylisatins commencing with chains containing more than two C atoms.
