An efficient and practical one-pot, two-step synthesis of 1,2,4-thiadiazoles from primary amides with Lawesson reagent (LR) and tert-butyl hydrogen peroxide (TBHP) without solvent is demonstrated for the first time. This groundbreaking and environmentally friendly approach utilises readily available starting materials and eliminates the use of traditional solvents in the reaction process. The broad
首次证明了在无溶剂的情况下,用劳森试剂(LR)和叔丁基过氧化氢(TBHP)从伯酰胺高效实用的一锅两步合成1,2,4-噻二唑。这种突破性且环保的方法利用了现成的原材料,并消除了反应过程中传统溶剂的使用。广泛的底物范围、在温和和无金属条件下出色的官能团耐受性、快速转化和出色的产率是该方法的基本特征。所有化合物均无需柱色谱法纯化。
