An efficient catalytic system consisting of KI and K2S2O8 for a one-pot pseudo three-component cascade reaction in the preparation of a diverse array of 1,3,4-selenadiazole derivatives from easily accessible precursors aldehydes, hydrazine and elemental selenium is demonstrated in this paper. Here, KI is used as the surrogate of iodine and K2S2O8 as the oxidant. The key advantages of this protocol
一种由 KI 和 K 2 S 2 O 8组成的高效催化体系,用于一锅假三组分级联反应,从容易获得的前体醛、肼和元素制备各种 1,3,4-硒二唑衍生物本文演示了硒。这里,KI用作碘的替代物,K 2 S 2 O 8用作氧化剂。该方案的主要优点包括反应设置简单、操作简单、官能团耐受性高以及使用低毒性化学品。此外,还进行了自由基猝灭反应以确认其机理途径。
