• 論文の詳細を見る

• 3-Halogenopyridazines (I) were alloued to react with hydrazine hydrate in the presence of Pd-CaCO_3 and alkali to afford the symmetrical 3,3'-bipyridazines (IIa-IIg). When an equimolar mixture of two kinds of 3-chloropyridazines of different substituents was subjected to this condensation reaction, the unsymmetrical 3,3'-bipyridazines (VIIa-VIId) were formed. Various 3-chloropyridazine N-oxides (X) were subjected to the condensation reaction and the expected 3,3'-bipyridazine di-N-oxides (XI) were obtained in low yields.
