A dimerization of the substrate occurs with pyridine 1-oxide, 2,2-bipyridine 1-oxide or quinoxaline N-oxide. A similar dimerization in good yield occurs when treating azine N-oxides with tert-butyllithium and this serves as a simple and convenient method for preparing bi- and tetrapyridines Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Rusinov, V.
