MASS SPECTRAL FRAGMENTATION PATTERN OF 2,2′‐BIPYRIDYLS. PART VII. 2,2′‐DITHIODIPYRIDINE

N. G. Keats; Lindsay A. Summers

The mass spectral fragmentation of 2,2′ -dithiodipyridine involves loss of the elements S, SH and S2 from the molecular ion in addition to rupture of the central bonds. Molecular rearrangements accompany the disintegration.


Zeitschrift für Naturforschung B | 1977

Mass Spectral Fragmentation Pattern of trans-1,2-Di-(3-pyridyl)ethylene and trans-1,2-Di(4-pyridyl)ethylene

N. G. Keats; Lindsay A. Summers

The mass spectral fragmentation patterns of trans-1,2-di-(3-pyridyl)ethylene and trans- 1,2-di-(4-pyridyl)ethylene obtained on electron impact have been elucidated. They are more complex than the disintegration pathway observed with trans-1,2-di-(2-pyridyl)-ethylene.
