Bipyridines. Part XVIII. On the Synthesis of -3-ol and Other Novel 2,2'-Bipyridine Derivatives from -3,3'-diamine
-3-hydroxylamine (6) and its 3'-acetylderivative (7) were obtained by diazotization of -3,3'-diamine (3) in acetic acid, however, diazotization of copper(II) complex of 3 led to -3-amine (10).The amine 10 was transformed into -3-ol (2).The pethway of the reaction was proposed.
