Triazolo[3,4‐a]phthalazine as well as their chloro and nitro derivatives were subjected to the reactions with the carbanions typical for the vicarious nucleophilic substitution (VNS) of hydrogen. The reactions were strongly dependent on the substituents present on the triazolo[3,4‐a]phthalazine ring and resulted not only in the substitution of hydrogen but also in exchange of chlorine atom and pyridazine
Triazolo [3,4-a]酞嗪及其氯和硝基衍生物与典型的碳负离子进行反应,碳负离子通常是氢的取代基亲核取代(VNS)。反应强烈依赖于三唑并[3,4-a]酞嗪环上的取代基,不仅导致氢的取代,而且导致氯原子和哒嗪环断裂的交换。后一种方法主要用于未取代的三唑并酞嗪。其中两种产品显示出对中枢神经系统有希望的刺激活性,而没有明显的毒性作用。
