On October 31, 2004, Schilf, Wojciech published an article.Electric Literature of 75449-26-2 The title of the article was The spectroscopic study of hydrogen bonding in some 3,3′-derivatives of 2,2′-bipyridyl. And the article contained the following:
Four 3,3′-derivatives of 2,2′-bipyridyl have been investigated by multinuclear NMR, IR and X-ray methods. In all cases the weak intramol. hydrogen bonds between exocyclic nitrogen-containing substituent and pyridine-type ring nitrogen atom were found. In contrast to the previous results the nitrogen chem. shifts of pyridine ring atom do not provide valuable information about hydrogen bond strength. The presence of intramol. hydrogen bonds was confirmed by nitrogen chem. shifts of exocyclic amino and acetamide groups, deuterium isotope effects in the solid state and IR measurements in both chloroform solution and the solid state. The X-ray structures obtained for asym. 3-amino-3′-methylamino and 3,3′-diacetamide derivatives confirmed conclusions made on the base of spectral results. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Electric Literature of 75449-26-2
