Abstract

The mass spectra of benzaldehyde selenazolylhydrazones Ia-d and benzaldehyde selenazolidenehydrazones II and III were studied. Splitting out of benzonitrile as a result of a rearrangement of the McLafferty type is characteristic for the fragmentation of the M+ ions of Ia-d. The subsequent fragmentation of the M — C6H5CN ion occurs due to ejection of the SeH group or a molecule of carbodiimide from the selenazole ring or due to cleavage of ring side substituents. The principal fragments in the mass spectra of II and III are formed as a result of the ejection of groups of SeH and SeCHCO atoms.
