Tetra-acetylethylene (I), prepared by oxidation with iodine of the dithallium(I) salt of tetra-acetylethane (II), reacts with hydrazine to give a mixture of 1,4,5,8-tetramethylpyridazino[4,5-d]pyridazine (IV) and 6-amino-1,4,5,7-tetramethylpyrrolo[3,4-d]pyridazine (V). Treatment of compound (I) with hydrochloric or hydrobromic acid yields furan derivatives, whose structures can be established by chemical
四acetylethylene(我),通过氧化用碘四acetylethane(II)的dithallium(I)盐的制备,与肼反应,得到1,4,5,8- tetramethylpyridazino [4,5的混合物d ]哒嗪(IV)和6-氨基-1,4,5,7-四甲基吡咯并[3,4- d ]哒嗪(V)。用盐酸或氢溴酸处理化合物(I)得到呋喃衍生物,其结构可以通过化学和光谱方法确定。化合物(I)与2,3-二甲基丁二烯形成Diels-Alder加合物。
