A rarely explored oxidative ring contraction of electron-rich 1,2-diazine is described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that is accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives. In addition
描述了很少探索的富电子的1,2-二嗪的氧化环收缩。用亲电子氯化试剂(TCICA)处理后,1,4-二甲氧基邻苯二甲azine嗪会经历N-氯化诱导的环收缩,并伴有一个氮原子的损失。用一系列的1,4-二甲氧基邻苯二甲醛衍生物检查了这种异常反应性的范围。另外,基于分离的反应中间体和DFT计算,提出了经由双环物质进行的机理。
