Mass-spectrometric behavior of benzo-substituted dibenzo-18-crown-6 ethers

Chemistry of Heterocyclic Compounds Aims and scope

Abstract

It was shown that the intensity of the peak of the molecular ion in the mass spectra of dibenzo-18-crown-6 derivatives depends to a marked extent on the electronic properties of the substituents on the benzene ring. Fragmentation of the substituents is observed after the decomposition of the polyether ring. This permits the proposition that the preferred localization of the charge in the molecular ion and the fragment ions is on the oxygen-containing part of the molecule. The analysis of the mass spectra of benzo-substituted crown ethers renders possible the determination of substituents occurring in the aromatic part of the molecule and their steric position.
