1-Chlorophthalazine reacts with two molar of ynamines to give penta-substituted pyridine derivatives by N-N bond cleavage of phthalazine ring. We realize this is common to other halo-substituted condensed pyridazines.
1-Chlorophthalazine 与两摩尔的 ynamines 反应,通过
酞嗪环的 N-N 键裂解生成五取代
吡啶衍生物。我们意识到这一现象与其他卤代缩合
哒嗪很相似。
