The title compounds, which exist in solutions as mixtures of exo/endo double bond isomers due to the “push-pull” effect of the electron-donating and electron-withdrawing substituents, were studied by mass-spectrometric methods. Their fragmentatio

Electron impact (EI) spectra of polymethylene-bridged carbonylhydrazones of 4′-formylbis(benzo-15-crown-5 ether)s, their 18-crown-6 analogs, and their complexes with alkali cations (Na+, K+, and Cs+) were studied. Evidently, there are three main ro
