On June 30, 1983, Hsieh, Chun Chin; Wang, Ching Bore; Lin, Lung Ching published an article.Formula: C16H22Br2N2 The title of the article was Mass spectral study on 1,1′-dialkyl-4,4′-bipyridinium bromides. And the article contained the following:
The electron-impact mass spectra of eight title salts (I; R, R1 = alkyl; X = halo) and 1-hexadecylpyridinium bromide were studied. An ion peak of M+• [M2+(X-)2 = I] was detected by the one-electron reduction of M2+ ion. When the alkyl was >C5, a characteristic peak of C4H8Br+ was found from the bromide complexes. A peak corresponding to (M-2)+•, representing loss of HX from MX2, was also found. A base peak corresponding to (M-R-R1)+• was observed with smaller alkyl groups. The experimental process involved the reaction of 1,1′-Dipropyl-[4,4′-bipyridine]-1,1′-diium bromide(cas: 52243-87-5).Formula: C16H22Br2N2
