The m- and p-phenylene-bridged bis-azolopyridinium salts have been synthesized and converted into the corresponding bis-dienamines by reaction with pyrrolidine. These dienamines react readily with dimethyl 1,2,4,5-tetrazine-dicarboxylate to yield the bis-azolylvinyl-pyridazines.
的米-和p -亚苯基桥连的双azolopyridinium盐已经合成,并通过与吡咯烷反应转化成相应的二dienamines。这些二烯胺容易与1,2,4,5-四嗪-二羧酸二甲酯反应,生成双-偶氮基乙烯基-哒嗪。
