On December 31, 1985, Kaczmarek, Lukasz published an article.Electric Literature of 75449-26-2 The title of the article was Bipyridines. Part XVIII. On the synthesis of [2,2′-bipyridin]-3-ol and other novel 2,2′-bipyridine derivatives from [2,2′-bipyridine]-3,3′-diamine. And the article contained the following:
Diazotization of bipyridinediamine I (R = R1 = NH2) in AcOH gave hydroxylamines I (R = NHOH, R1 = H, Ac); however, diazotization of Cu(II) complex of I (R = R1 = NH2) gave bipyridinamine I (R = NH2, R1 = H). Diazotization of the latter gave bipyridinol I (R = OH, R1 = H). The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Electric Literature of 75449-26-2
